What bothers you the most when playing poker?

Worst thing that happens to me is when my internet connection goes bad and the green bar appears trying to find a connection!And trust me i get that a lot and its so frustrating!
And the worst thing is when the connection comes back it feels like i am loosing my pace and my cool i had so far at the tournament i was playing.As a result i feel vulnerable don't know why but i get that every time...
And when my dog comes over and knocks his head on my feet but i love him so its not that bad!
