Happy?

Sitting in a cafeteria waiting for my son from his swimming practice
Read a book about happiness, happiness at work
Thinking of life
Am I happy? I think I've always been
Sometimes I get sad, like today, but I'm never unhappy
I hope to stay this way
Sometimes I want more, like the other day, but I'm never unhappy
I hope to stay this way
I've been pushed around, I've been hurt
But I've never been unhappy, just sad
I hope to stay this way
I've bullied, I've been an asshole, I'm sorry
I hope I'm bigger now
I'm happy, but let me be sad for a while
