There are some Avatar characters who act and look like people I know in real life.

Aang: This guy in my high school cooking class last year.?? I swear, he looked like Aang with hair.?? He even sounded a bit like him, too.

Sokka: Someone I knew from English.?? He was the type of guy who always said the wrong things at the wrong time.??

A woman from work is really ditzy, and she reminds me of Ty Lee.??
