I am rather annoyed...its like if my moms boyfriend has a little problem the whole house has to have a problem. I mean so he is upstairs in the kitchen I imagine something was out of place or some stupid little thing....that was frusterating so he scream/growls about it so the whole house can hear just in case there is someone else home who can also be effected by the 'catastrophe' that might be something as minor as a can finding its way into the paper recycling or a bag of bread wrapped up with no bread tie.

I guess the best thing to do would be try to ignore it, rather than go up and tell him to knock it off...reacting probably just reinforces the behavior. lol
