Why Do We

Why is when your sad your cry,
but when your happy you laugh?
I may not know these answers,
but I know that I still like you.
Why do we say the things that we don't mean,
but we say them anyway?
Why don't we say the things that we need to say,
but we don't say them?
I'm sorry that I never said I Love You,
because I thought you knew.
I didn't mean to say all thos bads things to you,
and about you .
I'm sorry!
But now I need to move one,
and forget about my past life,
but above all things,
why do you say I Love You when we don't meant it?
