I did several brave things:
1- screamed like my hair was on fire
2- tried to climb on top of the counter and into the sink so it wouldn't climb up my pajama bottoms then into my hair thus into my ear and eat my brain
3- drooled toothpaste while screaming
4- thought what the R#R# is a mouse doing opening doors that are a bazillion times heavier than itself? I clearly have a herculean beast scurrying about
My naked, long suffering, husband groggily got out of bed minutes later to make sure I wasn't having a seizure but the mouse had already gone, flipping me off as he scampered away because I was making such a racket.
