I have three grown children, so I've been there. Yes, respect them as they grow, but don't try too hard to be their friend. They still need a parent, even if they don't realize it. They need boundaries and curfews (even if they are general) and parents who do check up on them. They pretend they are grown up, but deep inside they are looking for someone to say "no" when they can't, due to peer pressure, etc. I have had to be the bad guy more times than I can count, but at this point, my kids are best friends. They will yell and rage at you when you are the bad guy, but they will respect you in the end, because you cared enough to stop them when they were going down the wrong path. Sure, there are a lot of life lessons they have to learn themselves, but they do count on us to be there for them. Teenage years were hard for me, but we weathered them out and I am humbled they are such great adults.
