Sokka couldn't believe Aang was asking him for girl advice.
Sometimes he forgot the kid was twelve – his playfulness and penchant to ride dangerous animals made him seem younger than he was. (Occasionally his courage and gravity revealed all his century-and-some-change, but not always. Not even often)
But Sokka remembered being twelve – of course, his village had been pretty devoid of twelve-year-old girls, but still. He understood how Aang felt.
That this conversation was happening at all puffed Sokka up, made him feel honored and proud – determined not to let Aang down.
"You've come to the right place," he boasted.
