On a first date, a guy told me he was a retired FBI agent. I didn't think anything of it, just went on some more dates and enjoyed his company. About date #5, he 'fessed up that he'd lied about it. He didn't know why he said the lie, just that he'd been on so many first dates and had gotten a bit jaded so was just...lying for no reason just because he'd gotten used to things going nowhere. He really seemed generally to be a great guy, and authentic thereafter, but I just...somehow couldn't get over that first lie. Really bothered me...who knew when he'd lie again for no particular reason...or for a reason...
