You know you're old when.....

[Larryc001]

I feel old when I remember seeing an Isetta front-opening car for sale in Hudson’s Bay department store. On the third floor.

[Gregg]

Never have I worked so hard for so little until after I retired.
I can’t believe the number of inarticulate younger people who think I’m stupid because I don’t use their bastardized language or play silly video games.  Maybe I am too old to matter to them.

Exercise your seniority by meteoritically patting them on their pretty little heads.

Watching War Games [1983] completely unfazed by the IMSAI 8080 prop and 300 baud acoustic modem.
The closing credits thank Godbout Electronics... hey I bought 1Kx1 RAM from them in the late 1970's got the PC board right here... Bill Godbout was a Silicon Valley minor legend, S-100 pioneer.

When this became this:

[GlennSprigg]

Being an Invalid Pensioner, and having lost most things/abilities that I had, and being 'told' by others how stupid I am now... 

[Neper]

When you know what C= stands for and you have connected an Amiga 3000T and an IBM PC via Arcnet.

[harerod]

... your professor taught you Neper instead of dB as a ratio of dampening on transmission lines. *SCNR*

[Neper]

I've been working with dB from the beginning but the Deutsche Bundespost guys who came to hook up our o/b van to their audio line still used meters calibrated in Neper.

That said, I'm old enough to remember the days when the vehicles of their telecom division were grey instead of magenta. 

[harerod]

Yes, when Deutsche Bundespost consisted of Gelbe Post, responsible for snail mail and Graue Post responsible for telephone. The former has become Deutsche Post, the latter Deutsche Telekom. Rumors that hint of them re-joining as Deutsche Kompost AG are just that...

On topic: I remember the days before ISDN, when one was tempted to use an illegal 9600bps Hayes modem, instead of the officially approved 300..2400bps modems. When I complained about that fact to a fellow computer club member, he looked me sternly in the eye and said: "at least our phone network works". I never understood what he meant, until I suffered some culture shock from exposure to U.S. telecom infrastructure.

Bill Godbout was a Silicon Valley minor legend, S-100 pioneer.

Who tragically lost his life in the Camp fire in California a few years ago. RIP Bill.

... when supermarkets and car commercials play "classics".

...and while pushing your cart through the supermarket, you are angered that the weekly specials announcements and repeated calls for a clean-up on aisle six, keep interrupting your favorite tunes.

"You know you're old when....."

... the thought would even enter your head to start a thread titled "You know you're old when....."

Hehe

You know you're really old when you are the cause of the "clean-up on aisle six", for embarrassing personal reasons.

The wife was reaching for a can of beans and I had to have her then and there.

...old when:
   People STOP referring to you as 'that older guy...'

[OldEE]

Old when I remember wearing a pocket protector with multiple pens.

Used red and yellow pencils for marking up blueprints (actually they were white prints with blue lines).

Erased the brown lines on sepia prints with whatever was in the magic little bottle of clear liquid.

Noticed that the Osco drug store in South Bend, Indiana, had 1 pound jars of saltpeter, sulfur and powdered charcoal on the shelf for purchase.

Ah! The smell of Ammonia!

[RJSV]

   When 'EYEBROW' trimming becomes 'regular' necessity.

and... When 'regular' gets to be a carefully uttered word...

[jonovid]

you remember when the phone booth was a thing

[TimFox]

I keep noticing phone booths in public place, but the telephone equipment has been removed.

[themadhippy]

you remember when the phone booth was a thing

And the town library was a large building full of books

[Quarlo Klobrigney]

Reflective Christmas trees lit with the 3 or 4 colour rotating wheel, decorated with lead tinsel..

[TerraHertz]

When these things seem like yesterday.  Found while tidying some papers in a room I don't use much.

For those not in Sydney, the Valhalla was a great old cinema that would run classic movies.

Not even all that long ago. Yet now it seems like memories from a different world.

[TimFox]

The late Russell Baker, American journalist and curmudgeon, complained that due to his unsavory professional contacts he could obtain illegal drugs, firearms, even the services of a hit man (should he so desire), but he was unable to purchase genuine lead tinsel.
