i just lost another bet to my sister . oh yea ? what was the bet ? that my mom never worked at mcdonalds when she was younger . everyone 's got that low minimum wage job at one point in their life sometimes . she told me she had never worked in a restaurant when i wa little . i think they duped me .
The cause of the anger appears to be the realization that the person's mother lied about not having worked at McDonald's when she was younger.
