There is one parent at my daughters school who has been very rude to me. These past few weeks she abruptly stomps by me and doesn't even say hello makes no eye contact. We always attended school functions in the past and were very friendly and even helped out together. I expressed concern to another parent this parent didn't call me to help for a particular function that she was incharge of and that was all that was said. I don't know if she added fuel to the fire and told the parent in question something different but all of a sudden she started ignoring me. I approached her and she brushed me off and I'm having a hard time dealing with it. Any suggestions?
