I feel for you KF, My PC (political correct) Valve is also defective. Cant stop my mouth from saying the things my brain is thinking especially in my own home! Ive learned to regulate it at work (Thanks to the US Army years ago) but for some reason, when Im sitting on my own couch, my mouth thinks it can just say whatever it wants! Luckily, my wifes learned to keep her thick skin handy at all times and I know how to grab food from the cupboards so even when my mouth gets uppity, I dont go hungry!
Actually, it usually only makes for a quiet night and sometimes if my PC valve really Phucks up, extended silence for a couple days which isnt always that horrible!
