There was this family who sent us an outrageous one every year. My dad had gone to optometry school with the husband, and his wife wrote these obnoxious letters talking about how great her husband's business was doing, how their kids were these absolutely amazing, talented, smart kids (puke)... we would sit there and make fun of the letters all the time.
Then my sophomore year of college we found out that the husband committed suicide.
We haven't gotten a letter since. He was a really nice man, his wife was just a bit stuck on herself.
