Before I go, can I try and make you happy?
Should I rewrite that line since it's a bit sappy?

Before I go, is it okay to give one last smile?
I know I know, I've cried for quite a while.

Before I go, can I tell you how much you mean to me?
I'm sorry that I will be leaving, but you'll be free.

Before I go, can I write out my last few lines?
I'll keep it happy with my "I'm fines."

Before I go, can I try one last shout?
I want you to be happy without a doubt.
