Many people have said many things on this thread....much of which is true...in their eyes or even some others.
The thing to remember is..."You spend the first part of your life being "bugged to death" by your parents and the rest being " bugged to death by your kids"...this is a fact of life and all anyone can do is try in whatever way possible to minimise the situation......a desire which comes from within each of us!.....Work at it!!!! You can emulate your children but you cannot MAKE them conform to your standards. As Kahlil Gibran said in the book "The Prophet"...."Your children are as arrows".......and goes on to say..you can point them in the right direction and release them but they will be blown this way and that and find their own path as you cannot control it.
Sorry if this is hitting anyone hard but after a "Child Care career of 30 yrs..I've been there...seen it...done it...bought the "T" shirt...made a hole in it...sewn it up...washed it...and worn it again. All you can do is try! Best wishes, Mike.
