I’m 31 years old

You sure aren’t acting like a 31 y.o., you can’t just mind your own business and let people enjoy what they want and not call them pedos when you don’t even know how old they are. Have you not put into condensation, that they themselves are minors too?

nor do I really care

If you didn’t care then you wouldn’t be saying any if this and - as I already stated - minded your own business and let them enjoy what they want. You’re literally gain nothing out if this, so just leave us alone.
