He had never understood why that one girl from Konoha stared at him the way she did. Not until today.

Gaara had been born with Shukaku inside him, the one-tailed bijuu. Such was the nature of his seal that if he had ever fallen asleep Shukaku would take over his body and run rampant. While there had been times during his ' admittedly shameful ' past that he had allowed this to happen freely, for the most part Gaara had always preferred to remain in control. Which meant, of course, that he did not sleep. A civilian would never have been able to do it. It required constant chakra flow to stay awake for months,

years

at a time. But then, a civilian would not have been able to contain the One Tail either.
