I'm not going to include all my friends when I cook
Why don't you want to include them?
They never appreciate my efforts, and the way they act when I cook, it starts to feel like they're just using me.
You shouldn't leave some of your friends out, though. Excluding people is rude.
What about their rudeness in being demanding, taking all my food and then taking off, instead of hanging out with me?
Oh, boy, that's starting to sound like they're not really your friends. Have you tried sharing your feelings with them? Perhaps they don't mean to be so inconsiderate.
