re: Serious question..if your S/O did this what would your response be?

Not trying to be a dick but what kind of guy freaks out over 126$ This dude has to be dumb to 1) loan said money 2) be stressed over 100$ 3) bring up the fact that he did it in the first place.

If the chick was comfortable enough to ask him for money then you have to assume they have been in communication for a while. Either that or he is the easiest person to con in the world.
