HEAD CANON TIME!
Ok so you know how I always thought Toph and Aang would embarrass Tenzin and Lin on purpose, and be total trolls?
Well I like to think that Katara accidentally embarrasses Tenzin xD Like she would be the kind of mother who tells cute little humiliating stories about their kids without realizing that it could be embarrassing. xD
It's even worse when katara is telling Tenzin's wife, and ex girlfriend xD
Also, I want to think that those two are ok with each other. I mean, what mother would dislike a woman that practically risked her life for HER children!? HELL I WANT THEM TO BE BUDDY BUDDY AND SHARE FUNNY STORIES ABOUT TENZIN.
...I'm too obsessed with tenzin. OH GOD....
