when did i become so forgetful

realised as i was leaving work that i hadn't got my house keys in my bag, now i remember taking them and my cheque book and diary out of my bag before we went on holiday and putting them in a safe place until we got home, well of course i'll be damned if i can actually remember where the safe place was, i've had the house turned upside down and all my usual safe places searched and they are not in there, so the next stop is the upstairs and hopefully they'll turn up, think since i turned 40 my brain has become mush LOL
