simply vanished !!!

put my car keys in my back pocket for some reason last week , spent twenty minutes tearing the house apart , decided to sit down to calm down and there they were . I have a little pentastar I bought at Moparfest 2010 it sits on my counter , every time I look for it to install it it's gone then months later it's back , cleaned the counter the other day and there it is again taunting me . So yes I know exactly what your saying .
