Oh I hate constant interruptions when I'm trying to relax and either watch a show or play a game. That really triggers me. The worst is when you get interrupted, go do what needs done, come back, and the moment your butt hits the chair you hear "Mommy, can I have some (insert snack or drink here). It's like they wait for it. LOL

And too much repetitive noises really bug me. Repetitive noise, and flashing lights.
