Accidental Gaining

I remember back in elementary school, at around Grade 2, when this eye candy was skinny and was one of the most athletic person in my class. Then one day, his knee was injured causing him to take things easier especially in athletics. This problem to this day has not healed fro him. As he got older, he started to get fatter and went from skinny to overweight. If I had pictures to show, it would be really dramatic.
