rant an tat tat

For some reason several of the moms at my son's preschool were already familiar with me. WTF! Someone who used to be considered a friend until she went all jr high psycho on me had told some of the moms that me and my son would be in the class behind her kid.
I can't tell by the reaction I received from the moms if my introduction by this person was positive or not. Just knowing this person, I would say not.
Lord have mercy on her soul if I find out that she bad-mouthed my kid though. I can prove misconceptions wrong in a heart beat but to put a strike against my kid. Oh hell no.
