Parenting

I am sure I have heard every parent say at one time or another "it's not easy being a parent". when do we ever stop taking responsibility for our children? I know that we can't be responsible for everything they do and certainly when they are adults it is hard to bear that burden.  But lately, I have been feeling bad about some things my son has or has not done, and while he is an adult, I feel bad as a parent, because I didn't raise him that way.  I didn't teach him some of his behavior but it had to come from his upbringing right? My son is not a bad person by any stretch of the imagination, and I am very proud of what he has made of himself, but I am disappointed in some of the ways he has dealt with some things and I feel responsible because I didn't do a good enough job in teaching him. I am sure that some of these things are trivial to others, and the way young people do things these days are totally different than the way we would have done something at that age, but it makes me stop and think about parenting and how little things really can make a difference.
