Working for a Living

I'm working today...three days in a row. Yuk. My boss called me yesterday and asked if I'd cover for a sick nurse. She was so desperate she said they'd pay me for eight hours, even if I don't stay all day.

How could I say "no" to that?

I'll probably get stuck staying all day anyway, but whatcha gonna do?

In the meantime, my house is a mess, I have no groceries and my laundry is piling up. But I can't dwell on that. It stresses me out.
