half his class joined a class 10 tuition batch this month. he hasn't asked to

class 10 started at the beginning of april. by the second week most of the boys he sits with had joined the same coaching centre near school. evenings, three days a week. he mentioned it like it was news about someone else. hasn't asked to go, hasn't said he doesn't want to. i keep waiting for him to bring it up and he keeps not bringing it up. his marks are fine. i don't know if i'm meant to push or wait.
