OMG yes. Usually they happen when I'm PMSing. Although there is one supervisor at work that makes me feel like this whenever I work with him. I find myself snapping at him and that's not like me. He's just SO annoying. He makes you want to be mean to him. Most of the time I treat him (and everyone) politely. I've only really snapped at him when he's doing something stupid regarding the boarding animals.
