It's me not you.

It's me you are good,
it's me you are happy,
it's me you decide to do good,
it's me you do what you do.

The change is because of me,
the merry atmosphere is my kindness.
The happiness of contentment is me.
You feel good about yourself is because of me.

Once I am gone,
You are again you.
None to appreciate you,
none to keep you special in your way as you are!

But my influence will be all your life with you.
Every good deed you do comes into my umbrella.
