I always thought my perents weer happy, we had more then most in the sence we always went away over easter and christmas, we always went skiing over summer, we always had fun family times.
it wasnt until i was in 1st year highschool that i realised that everything wasnt as "happy" as i had always thought, because i came home to a almost empty house, my mum had up and left while my sister and i were at school and my Dad was at work, it came as a shock to all of us.
Years later i found out the reason she left was because she was having a affair for aprox 6 months before she left.

i guess sometimes its not whats perceived from the outside that counts, it's whats building up on the inside.
