What is the biggest 180 degree change in personality, good or bad, that you have seen in a person you thought you knew?

My old high school friend Mark.

He got royally dumped on by the love of his life and became a bitter, angry person. Last time I saw him, he had gained about 150 pounds (no shit!) and was on probation for DWI number 4 after serving 6 months for driving while his privileges were BARRED1!

All the fines and lawyer fees had drained him of what little money he got from a local factory as an injury settlement2. He was living with his mom and she drove him around.

1 not just suspended or revoked...barred-the worst possible category. He could have got two years.

2 his "injury" was the subject of some local gossip (small town) as people suspected the factory had given him some cash to get rid of him. He had been, according to fellow employees, a problem waiting to happen.
