Careless

You do know
That you shouldn't have said that then
You shouldn't have opened your big fat trap
As soon as he entered

Why did you say that
When you knew that she was sensitive
On that subject?

What did you do?
Oh, you didn't did you?
Couldn't you have thought
About the consequences?

What is it in your brain
That makes you speak
Before you think?

What is it up there
That makes you act
Without thought?
