i think we all have been in that situation at some time or another. my used to be best friend was using me as an excuse to come to my shop and work on race cars. we were building them at the time. i was working an evening job til 8pm. i would come home, lights on in garage, radio playing, tools out. one day i get a call from his wife wanting to know where he is. i guess over at the junk yard getting some more parts for the dart. no he is not. he is at dave's house. turns out he was hosing dave's wife all along and had filed for divorce, unknown to me. don't have anything to do with him after that. a guy told me how to pick your friends and i have always had that in the back of my mind. he said "pick your friends wisely. a friend is someone that will come over and help you move, no questions asked. a real friend is someone that will come over and help you move a dead body, no questions asked." hahahaha.
