No means "No"

Yes, that is right. No means "No". It doesnt mean "Maybe". It doesnt mean "I'll think about it". It is a decisive word that means "no", "non", "nada", "not going to happen". When someone says NO, that doesnt mean ask them again in an hour, a day, a week. They said no. Take the hint, get over it. Stop pestering or the first NO can turn into a hell of alot more.
