I think that in truth, anyone can fight.  I think though, that finding a healthy balances between good parenting and taking a step back, a parent being firm but still cool, open minded but with moral standards... teenage life is very difficult for both the teenager and for the parents.  Mothers want to understand and be there for their teenage girls, but teens sometimes don't want help.  They don't realize that the parents were teens once too.  The parent may want to help too much, and enforce the way they were when they were teens on their kids, or force their kids to be the way they wish they were when they were teens.  This is a complex issue, but to make it short, it's certainly a difficult time for teens and parents... but they get past it usually.
