GuyRule #93.: Did You Get Laid?
"If a guy goes out with a girl for the first time, when he comes back is 'Did you get laid?' You always gotta ask him. Now the guy's answer depends upon how much respect he has for the woman. If he respects her, he replies that he didn't get laid, whether he did or not. If he doesn't respect her, he's gotta say, 'Yeah, I laid her,' whether he did or not. So, if a guy tells you he didn't get laid, then he probably really likes the girl, or he laid her and he's really ashamed and doesn't want to tell you that. That the Guy Rule." -G
