I let a girl I liked but barely knew, drive my Porsche, with me, on her last day of work (we worked at the same place during the summer home from college). She kissed me on the cheek after the drive. I was in like Flynn, so I ordered her this Gund teddy bear and FedEx'd it to her parents' mansion. Never heard from her again.
edit: I actually just thought of this....she gave me her true home address, it was not bogus. Back then, there was probably no worries about internet stalkers...I figure it's the 7:1 conundrum. Pretty girls likely have 7 men interested in them at any given time.
