At my house, my job is to take out the trash. So as you know it requires me to put a new trash bag in the trash can. My biggest pet peeve in doing my job, is when I'm putting a new trash bag in and my Mom or someone else puts trash in the trash bag before I finish putting the bag in. This may sound silly to many of you, and I honestly can't give you a reason why it bugs me, but I can't think of any thing worse.
