"he does have to sleep some time." omg. that's it exactly. XD i imagine ohno is like myself in that he would rather not sleep if he didn't have to. sometimes he can be really good about sleeping! when he's a play he's totally good about taking care of himself, sleeping and eating right--but most of the time he's haphazard and causes his mother to worry about him, i bet. XD

(omg, "why is sleeping together important?" maybe because nino gets lonely! nino wakes up in the middle of the night and misses him! but says it in such a way that it's clear that ohno is in the wrong for not being in bed when nino woke up.)
