Parents always say they dont have a favourite (thats a lie) but children always have one favourite parent. Out of ma und pa, im closest to mother. dad is just too irratating and, lets not start. he does have plus sides.. bank account, car...
I think it's natural for mothers to tend to be protective of their sons and for fathers to tend to be protective of their daughters, but I don't think that constitutes favourtism. Can't say I've ever favoured one parent over the other, nor have I ever felt that I've been favoured/not favoured by one parent over the other.
Oh an J Christie, your mum is probably right, but even if she's not (parents are not infallible) hate is a very strong word - thing very carefully about using it. And your poll is in very bad taste.
