My old person trait is that I think 'ghosting' is completely unacceptable and you owe the other person a face-to-face conversation.
Preferring to see people in-person rather than remote. I wasn't too happy when a bunch of my coworkers switched to remote work. It's really not the same.
My opt is that I think that resturaunt a should have a way to at least call about allergens, but really take phone orders. And that they should always take cash.
My old person trait is that I have to make a noise whenever I sit onto or get out of a chair.
I suppose I have many old person traits because I am old, but, although I think it’s easy/cool to have tickets (plays, concerts etc) available on my phone, I still like to print them.
My favorite muffins are bran muffins, my favorite cookies are oatmeal raisin, and I love peaty scotch. I don't think those can necessarily be considered "traits" but I'm sticking with it
My old person trait is becoming more and more of an asshole as time goes by, either IRL or on the internet. And I'm not sure I mind it. I feel I should have been like this decades ago.
Mine is that photos should ideally be printed, not stored in a cloud somewhere that you have to pay for forever or you lose them.
I think that buying something should be more convenient than pirating in.
That's more of a "young person" trait though. For most of the history of media that could be pirated, buying meant going to a brick and mortar store and paying ridiculous sums like $10 per song on a music record. Pirating was nearly always more convenient.
