Things Changed???

Some of my friends just back from NS....
just meet him recently..and bring him to meet up some old friends.
when we having a chat..one of them say that KH which back from NS and changed already..means become someone else.....
and now i'm back at home..thinking of those words...he has been changed??changed to what??mutation to someone else???people are not changing but growing up...maybe before he is going to NS he is a little bit funky and not serious when he is doing something important...
i think he is growing up but not changed...
i believe that he is thinking of being good and serious whenever he doing for something...
maybe he just had that thought but didnt do that....
maybe now he is thinking of something right and have the thought of want to do it right....
and this call changed???human are hardly to changed....just keep growing up...
i read thru some articles about home education...
there is always one sentence:Parents are always right....want to protect our children..just not in a direct way of doing that or in the way which children can't accept....
we always heard that parents want his own kids to stay away from drugs and those bad habbits and some bad attitude friends...parents always strictly say that out...but why don't do it in a indirect way...maybe your children will accept it...try to get into their world...parents also have become a teenager before...try to get into that time...what are you thing about what your parents ask you to do...what have to be done and what should be done...
it's the same....just keeping from generation to generation....
people never learn...why don't teach in a another way...
Things never changed....what change the most is the thought of human...
