Each situation is different. I cannot speak for any other parent. But for my daughter trust IS an issue. I do not go in her room or read her E-mail or open her personal mail or any personal letters she has. I travel a lot, ( I am 1200 miles away right now). She runs the house and has for the last 3 years when I am gone. She has stepped up to this challenge. I have let her go to Europe and travel from Australia by herself. At 18 I think she is way ahead or most kids her age.
In summery, I believe our children get a lot of their identity from what we as parents project to them. Trust them and they will live up to it. They will slip or make stupid choices, but so do we. Maverick
