For Christmas the first three years of my marriage, my mother-in-law bought me a new brown coat. Just brown...no other color. Each coat was really nice, different and unique from the year before. But imagine that I lived in Texas at the time where the need for coats is minimal. I didn't exactly wear a coat out in the season.
On the fourth year, I asked for a different color just to jazz things up a little...maybe black or navy blue. She quickly got the hint, and a family joke was started. Every year, she threatened to send me a coat, while really sending me sweaters or such.
Last year, my brother-in-law got me a brown scarf for Christmas. When I called to tell him how much I liked it, he told me he picked brown because he knew I already had a collection of brown coats.
