The Awkward Bathroom Hello

So, I guess I'll start with what's it all about..

I'd like to talk about the awkward bathroom hello. Don't act like I'm crazy, cause I know you've all gone through it. Like, you walk into the bathroom and someone you don't know makes eye contact with you, so you smile or say hi or whatnot, and it's just weird. And it's even worse if it's someone you know! You're walking in there, you've got one mission, and they're like, "Hey!" In your mind, you're thinking, 'Crap, intercepted..' I mean, you had one mission. So whilst maintaining conversation with this person, you're slowly creeping to the stall, then you go in.. and they keep on talking! So you're in there, peeing, they're asking you questions, and you're wondering if you should keep up the conversation. Either way it's awkward though.. Let's look at it from a third person's perspective.
So, I'm this third person and I walk into the bathroom, and there's people keeping up a friendly conversation while doing their thing. How weird is that?
It's like when you're at the dentist and he's asking you questions.. Am I supposed to answer him? Really. If I answer, he probably won't even be able to understand me, and I'll probably end up licking him or biting him or something. On the other hand, if you don't answer him, you just left him hanging. Maybe I should ask a dentist. "Would you rather be left hanging or not be able to understand me?"

Maybe bathrooms and dentist offices are just awkward places, no matter how you spin it. Public bathrooms, guys.. I dunno.
