Dood, like,
I've never considered sharing a drink with someone a big deal.
I mean, it's cute, when it's totally consensual, just like eskimo kisses are cute.
but like, I share food with my family all the heckin' time. We share paper plates that aren't that dirty after we are done using them.
So, yea, I've done that sort of thing, but I've never considered it a big deal at all.
