Sometimes my girlfriend will start eating almonds when we watch a show. Like during Band of Brothers...
***There is dead silence as our American heroes wait in their foxholes... ready to take cover from German artillery fire, snipers, what have you... the tension builds and you know something is about to happen when *CRUNCH CRUNCH*..........(ellipses).
It is ok though, whenever she is watching something alone I just toss the squeakiest toy our dog has into the room...
