No.

Damn, I would so love to say just "no".
"No, I have no time."
"No, I can't help you."
"No, I don't want to talk with you now."
"No, it is not okay for me."
"No, no, no."

But instead I say yes, I do what I was asked for. Because my parents raised me being polite, friendly and helpful.

And because I do care.
