Doesn't it make you feel GREAT when you notice people checking you out?! I have noticed that about myself too and it works WONDERS for my PMA. It just shows you that you can still capture the interest of the opposite sex, and find someone else if things don't work out in the end.
You shouldn't have any problems in the PMA dept. after this! Maybe try a game store with some employees your age! And if you can't find that, then your son will just have to change his hobby to something else! LOL!
