Don't you hate it when....

You write something in an email and you assume its going to be taken as me taking the piss, and then you get a response that seems as if it could go either way, either taking the piss right back or actually being pissed off at what you said and you don't know which one to choose?
Also, having this happen when you have a brain that decides not to turn off when its bedtime and so you know that you'll lie in bed awake for hours stressing about this tiny insignificant little thing when if you were going to be awake for hours it would at least be for worrying about something really important?

And don't you really hate it when you have to pee and your roommate is in the bathroom?
