Why should I care?

Why should I care
Can I just be unhappy for one day
Let me be
You too dare
To be unhappy some days
And take it out on me
Am I complaining
All the time
You yell and whine
Did I really go that far?
I don't care
You don't know how I feel
And I'm glad
You went away
Cause today
I don't want to be quiet
Cause today
I want to scream and yell
Very well
And I don't care!
