About 10 years or so ago, I had a guy come to my office to get his paperwork done to go overseas and get married. He was a clean cut guy, very friendly but kind of came off as a nerd, but the kind of nerd you don't mind being friends with, if that makes any sense. A dork that you wouldn't mind having a beer with. He was also short, hair thinning. I think he was in his early-mid 40s. He seemed pretty smart and he obviously had a good job becasue he could afford to pay for all of this shit.
The worst part was just how OPEN he was about it. He didn't need to tell me why he was going to Viet Nam but he just blurted it out, "Can you believe I have to go to Viet Nam to find a wife???". He wasn't mad, rather he was poking fun at himself. I just said "hey, uh, you know" and looked away. Maybe he just got tired of striking out with the women here, maybe he was a huge pice of shit. Personally, I think he was autistic and couldn't make connections with women. Maybe the language barrier will help him.
