I think girls won't ever learn no wonder some guys do address them as fish brain, imagine a girl asking for a favour after a guy just said Hi , just hi o. even if that guy have a good intention before the hi, but with the favour asked bet me that guy will definitely switch intention toward straffing her since she just showed how cheap or vulnerable she's. They girls cause the saying that all guys are the same meanwhile they cause why some guys are the same. So girls please and please Use your Head in dealing with guys.
