If a girl asks you what to eat at night every day, I think it is very likely that she regards you as her sister or a caring person. It is very likely that the girl has no opinion of herself, so, uh, I want to ask you or think that you are more opinionated or mature in his eyes, so I will ask you what to eat at night every day.

Of course, if this girl likes to spy on gossip, it may be another matter. She probably wants to inquire about your personal situation, and then it is likely to spread, so answer carefully, or you can alienate yourself.
