What Does It Mean?

For Why?

I sit there talking, having a great old time. 

But suddenly everything get's sublime. 

Why must I speak?

Why has the wonder reached it's peak? 

I didn't mean to hurt you. 

But apparently that's the only thing I can do. 

So I'll do it, I'll break it off. 

I may want to give him a second chance, but tough.

If you don't like it then I don't either. 

Even though you still talk to her. 

But I love you, and I'd do anything to keep you. 

Even though it's not always the best thing to do. 

So for why do I be so big mouthed?
