Aang never really knew what it was like to have a mother. He knew that he must have had one, somewhere along the line, but he couldn't remember her at all. He tried to imagine her, what she would have been like, but his mind just drew a blank. He had been raised by monks, he didn't quite understand the concept of mothers.
But he did remember his mentor Gyasto, who guided him and taught him everything he knew. And he remembered the kind nun who introduced him to Appa. He remembered all the brothers and sisters of the Air Temples. Each one would hug him and dry his tears when he cried. Each one would lend him a sympathetic ear and give him sage advice. Each one would laugh at his jokes, even when they weren't funny. Each one would watch out for him, for all the young Airbenders.
Perhaps Aang did know something about mothers after all.
