Romeo & Juliet. It's hard to explain

"...say the right things but act the wrong way
I like it right here but I cannot stay
I watch the TV; forget what I'm told
Well, I am too young, and they are too old
Oh, man, can't you see I'm nervous, so please
Pretend to be nice, so I can be mean
I miss the last bus, we take the next train
I try but you see, it's hard to explain..."
