I'm just gonna say it

Unless you're having an affair or you're in high school, please don't make out in public. Everyone else -- I believe there is somewhere else you could go to make out.

Plus! Do you honestly want people to watch you making out? I am probably an old fuddy-duddy, but I think it's kind of a private thing and I would rather not have it be witnessed. But that's probably just prudey old me.

Holding hands, kisses hello or goodbye, hugs -- these are all permissable in public.
