I have never nodded to a person in my life.If someone nods at me i just usually give them a smile unless the nod is accompanied by a comment.It annoys me if someone nods and says something like hey good lookin or nice tits i usually am quite rude i dont think people should say anything to a person they dont know weather it be a nice thing or rude thing they say especially if i have my son with me.If it is a woman or an elderley person that talks to me i usually am very friendly especially to the seniors i respect them and would never be rude.What about a wink ? Whats that mean ? I think it means if i was any closer i would kiss you lol.
