Apparently she doesn't know that you can get bagged carrots that are already cut up. Proves she never went to a grocery store herself.
She had her mother living with her, they had a PRIVATE CHEF, probably a house-cleaner, a gardener, and who knows what else, when they lived in Chicago. And part of that time, Wee Barry was NOT even living at home, because he was in the State Senate and then, in D.C. and a senator. So Michelle was home ALONE with her mother and the girls.
