someday you'll find

I'm used to you being mean to everyone. So don't ask me nicely if I'm alright.
I'm used to your snide comebacks. So don't just apologize and look so tired.
I'm used to you snapping back when I snap at you.

So please don't be so nice,
my heart can't take it.
Cos when I look at you, I feel like it's going to explode.
