Sandy's a sharp eye if there ever was one, and while she's surprised to see Aang in her district she can see the reasoning behind it even if she doesn't know what he's doing. Her height prevents her from getting more then the top of his shiny head in sight.

Still it makes sense, she wouldn't want to hang around his district either if she was the one behind that display. At least in District 12 they were more understanding...or at least willing to avoid talking about it.

Shuffling over to the fridge in her paint stained shirt with the words "Sister of Sand" on it she opened the fridge and procured a cup of mixed fruit, hesitating before she called up "Hey you want a snack or a drink up there?"
