JamieLynn
You are right it is childish and impolite also rude and discrimination too, My husband did told his ex that an insults and she said you don't understand and she even push their daughter to read what my husband says on the yahoo IM to tried to make my husband looks bad, why she get their daughter involve in their conversation in yahoo IM, she's 9 years old.
Mom said that my husband's ex is playing mind game on him to make him thinks he's really dumb, no good all that which is called verbal abusive. I don't know why people have to be so cruel to someone who's nice.
