To be fair I still do these things but only when I’m alone.
Personally I love finding big puddles and then dig drains with a stick or my heel and watch the water flow.
Also love to throw a piece of wood into water and then toss stones high up in the air and try hit it imagining it’s a warship I’m trying to bomb.
Then also without going into details there are some pieces of clothing I would like to wear but don’t because they’re considered femine or gay.
That’s annoying! I always assume someone is just deep in thought but I don’t know why I’d give someone shit for thinking.
Reminds me of people who like to say “its not that deep” all the time in response to questions that are meant to spark conversation. Like some people take pride in not using their brains or something.
Eh, no biggie! People do that when they don’t experience a similar behaviour themselves.
As for the not that deep crowd, I always thought they’re either self conscious or fear touching a triggering topic. Refusing to engage means they won’t be judged on their opinions or ability to reason and express themselves. Trying to pass a cool is what gives away they’re trying to cover up something.
I think part of it is them being self conscious but I think it was also just seen as a “cool” way to behave like you said. I often saw this mentality on reddit of course and in various discord servers where people just couldn’t back up what they were saying - so someone else approaching them with an in depth take, just causes them to try and shut things down with “oh its not that deep”.
Like its a very dismissive phrase meant to shut down conversation.
