What does "out of it" mean here?
"Out of it" is used weirdly in this scenario. In this scenario, it means "to get over a cold." However, when someone says "grown out of it," it usually means they can no longer fit in something or are no longer interested in something. It's not usually used when discussing illnesses. We usually say "got/get over it" when discussing colds or other illnesses. Ex: He used to be obsessed with dinosaurs, but I guess he's grown out of that. Ex: I just got over a nasty cold. Ex: The baby quickly grew out of her new clothes. Ex: She just got over covid.
