You are too funny. Be careful they have some serial internet daters on there. Also, ask them how long they have been on the site, if it's more than 6 months they are prolly serial. I say that because I was there on and off for two years and have watched people morph into several different men.
I once dated a guy for 4 months, when he got to Houston I had to deal with the fact that there is a internet height and a face to face height, and that can differ any where from 1 to 6 inches. This dude had me thinking he was 6ft and when he got here he was about 5'7 and compensating for a serious limp, a lazy eye, receding hair line and horrific breath. I wanted my damn time back. Can you get a refund on some time?
Put that kid on a webcam so at least you can reduce some of the facade. Make him stand up against something around him that you know the height of like a door. If his head is at the door knob, you know you got yourself a midget. Don't let him tell you we just put our door knobs up that high. He lying.
