Awww Sinead that stinks. My mom gets really irrational when she takes to the bottle, too. Ever since she has found out about wine and vodka I have had to get to know her as a different person. it can be tough. Don't let your Dad get you down on Christmas if he is in a funk, focus on having fun iwth the large wonderful family of yours! Hopefully your mom can talk some sense into him before the holidays hit Good luck Sending hugs!
