I hate it when people take advantage of my kindness

I'm the human version of a vending machine. I give them stuff for free and they don't even thank me.

I gave my brother my phone to fix his broken one. He still owes me $50.

I let my sister use my car for her road trip. She didn't even say thanks.

I brought my coworker coffee every morning. Now they think I'm their personal barista.
