Haha Nan, you're funny ! But it's a computer, and you're human, you needs more sleep than it ! 3-4 hours is so low !
Good advice my friend ! Music always change our mood ! :D But never feel like this, because I'm always behind you to be on your side Nan ! Really !
Oooh so sweet, you're like a sun for me ! :D
Take care of yourself please !! Tight hugs
