Of course, having a reasonable amount of cash on hand to enable immediate, necessary purchases is also a mark of adulthood (it means you have a decent job), so the story still works.
It's hardly hidden:
> I grew up very poor, so I was probably primed against the idea of spontaneously buying something to begin with
It's not like it's an item bought for no reason at all. (Not to mention in both instances they could go and return the item the next day)
I know people who are not going to break their budget by spending $10 on Uber when they are late, yet they would rather wait for a bus in the freezing cold or rain, waste time and be late.
Like, I have a friend who was finally convinced to take an Uber. She'd ask the driver to drop her off at the bus stop she'd usually get off at, and walk the rest of the way.
It is perhaps a bit paranoid, but when trying an unknown and unusual service for the first time, not over the top, especially if she is a girl living alone.
Then one day I did, and holy shit it's the best thing ever, I'm never using cash again (this was before covid hit which has made contactless mandatory now).
I'm sure there are a few other things in my life like this, i.e. things that I'm aware of, but making stupid choices about, I'm just not aware that it's a stupid choice.
My next step was not wearing shoes at all.
But I have to admit that's only working in the summer and outside of clubs/restaurants.
Reminds me of a time when I was in the city with a friend.
My shoes were broken, so I said to him "I need new shoes" went in the next department store, bought a pair, threw my old ones in a trash can and wore the new shoes.
He was mind-blown.
