Most Helpful Girl
Most Helpful Guy
Yes, it does, because she has nothing to gain by telling it to you. A prettier woman might be interested in manipulating you for other reasons, but when someone who is not attractive (per se) says it, you know it's from her heart.
I have gotten compliments from both types, and while when a pretty girl says it, it makes me feel good for a while- it's the less attractive ones who I know mean it from their hearts. Not sure if that even makes sense.
