This person hasn't changed at all?
When I was a freshman in high school, I started taking karate, and I was always paired with a fellow newbie in class. He was annoying and a know it all, but I still put up with him. I took the class for about a year until I stopped because I realized that karate wasn't really for me.
About three or four years later, I see he's in one of my classes in college, and he's stayed exactly the same- in both appearance, mannerisms, and personality. He's just as annoying and immature back then as he is now.
is it normal that he's stayed exactly the same?
