I'm more weirded out by everyone here asking "what do you even have in comon? What would you talk about?"..... like really? You think you can't have things in comon because of an age gap? It's like your underestimate younger people thinking they would only like shitty things from their own generations... iit's kind of a shitty mentality imo
i'm 33 and i've seen plenty of young adults (18-20 and so on) way more mature than me, with a shit tons of different interets and wide culture, while i'm stuck being all anxious and akward, only being able to talk about videogames and other nerdy stuff (In a lot of server i'm in on discord, i'm usually one of the oldest, people from this generations have usually way more in comon with me than those of my age, cause now more people are into videogames, anime, and so on... not saying there no people my age into these things, but they're harder to come by) !
Also Look at some crazy talented people on youtube, some doing video essays, some doing music, all with incredible talents and knowledge, and a lot of them are very young... it's kinda shitty to assume you can't find anything in comon with someone younger...
it doesn't even have to be romantic or sexual, you can simply be friends with younger people and have ton of fun, just don't be creepy, that's all
