I'll just leave now.

Ignore me.

I'm sad and I will make you sad.

We will disappoint and hurt and leave each other
 and then you will forget me.

I become too attached to people too easily.

People like you.

It's already happened, but I don't want to ask too much for you.

I don't want to ruin all the fun you're having.

I'll just leave now.

I'll go away so you can enjoy yourself.
