I think rising above it is all very well, and I aim to do the same
but sometimes, you just cannot do it
and if there are any PND or general depression type issues, or other complications, then you can just lose it
my children have seen me laugh, cry, get angry, be loving, be caring , frustrated, annoyed, excited, delighted
and many other emotions
i just cannot hide how i feel
and being able to show your emotions, i think, really helps stop you having to blow your top, as you are holding onto less resentment and less emotion
