Personally, it doesn't bother me. Making out, though? I roll my eyes. Get a room, people.

I can't really see how public displays of affection bother anyone who's older than high school age, at the very least...

I can understand that. That's like, being straight (obviously not saying you aren't) and being hesitant to hug guys. You don't want to send the wrong message, no? I don't typically hug someone of the opposite gender unless I know them on some level, at least.
