Aang was probably just serious during that incident, because he was on the job. We haven't seen a flashback of Aang on his down time with his family. Personally I think Aang is still fun loving and a bit crazy (Bumi probably takes after him). His job is demanding and he learned there are times to crack jokes and play games and when to be serious.
