I was shopping in an arts and crafts store, where a friend of mine worked, for a gift for my niece. She had taken an interest in oil painting and I planned to purchase a beginner set of paints and brushes.

My friend was at the cash register when I was checking out. I hadn't seen her for a few weeks and had started a diet in the meantime, having moderate success.

She asked me if I had gotten thinner.

I was thrilled that it showed already and replied that I had lost a few pounds.

She rolled her eyes and said, "I meant paint thinner."
