Worrying
You know that way, when you care so much about someone, that you get really angry at them for something that really isn’t that big a deal. Something like, say, not phoning anyone (friends or family) to tell them where you are after a night out.

You know the way, don’t you?

Yes I am making a point here. As her big brother it is my job to make sure she feels guilty about not phoning anyone.
Still love ya though, scatterbrain!
