One year was particularly difficult when my oldest daughter was giving me a rotten attitude during the entire Christmas season. So, I filled her younger sister's stocking with gifts that year and hung a bag of fake coal in the place of the nasty daughters stocking.
My ex has always maligned me to the girls yet I was the bread winner during our marriage. I do believe a lot of this stems from a form of alienation which usually runs a lot deeper with these children then them just being thoughtless towards us on important occasions.
