What does it mean?

The words I say are easy to speak, and what I speak is hard to say. It's easy to think, but hard to believe, especially when we act this way.

I think I'm too young, but it's hard to say, how do I feel, when I act this way? This feeling is so new, so hard to please, like a tedious kick, a ridiculous tease.

What the hell are we supposed to do? What does it mean, when I say I love you?

To my best friend Splinter, the only guy I can ever trust anymore. I'm glad I saved your life.
