Because I don't have a job, clearly that means I have nothing important to do with my life. That I'm a useless waste of space and here to do her bidding at any time.
Today she came up to me and said "Come here, so I can show you what you need to do to make dinner." There was no asking whether or not I was able to do it, or any way of letting me know beforehand.
I was planning on doing something with Kevin today. Maybe go out to a movie, or might end up going to his house. And when I tell my mom, she just responds with "Ha! You aren't even out of your pajamas yet. I think you can fit dinner into your busy schedule."
She may as well just say "You're doing nothing with your life, so clearly you have time to do whatever I want you to do at any given moment."
Whatever.
