LOL AT YOUR LAST ONE... I'm doing this right. this. second ;)
Mine is I always feel the need to eat 3 fresh bagels when I buy them, because hey, they never taste the same the next day do they? I always get mad at myself after the fact.
If you tell me about something going on and I don't IMMEDIATELY write it on my calendar, it doesn't exist. Chances are I will forget about it between here and the kitchen if you don't physically see me write it down too.
Stop waiting until first thing in the morning to make coffee. This is how black tar coffee is made, because I can't count the scoops without, you guessed it, a cup of coffee first. Do it the night before!!
And lastly, I always manage to wait until the very last second when I have to pee... it NEVER fails, that there WILL BE a child in there going #2 while singing some song, and I practically pee everywhere while trying to hold my breath.
[facepalm]
