It's just wrong

It's wrong to say I'm happy
It's wrong to say I'm sad
I could make those cute eyes of a puppy
But now the idea seems so bad

I wonder why
I said bye
Without a blink
And turned my back to you
So  I wouldn't think
About you

I don't know what I need
I don't know what I want

Why this keeps happening to me?
I don't know.
