What's the reason I'm not pleasin you

Why don't we get along everything I do is wrong
Tell me what's the reason I'm not pleasin you
I may kiss you but then, you don't say kiss me again
Tell me what's the reason I'm not pleasin you
If you must keep me in doubt, how will I know what to do
You can change me about, I'll be what you want me to
Though I try and I try Still I never satisfy
Tell me what's the reason I'm not pleasin you
