Facebook profile pic question

My brother says that he has only been seeing this girl for a few weeks and it is not serious. She already has a picture of them up as her profile pic. They are both in their mid-twenties, not teeny boppers.

Are they liekly more serious than he says, or is she being weird?

Don't say mind your own business, because he asked me to ask.

i think that even though your brother doesn't think its serious, she does. caution: this might be a red flag for a clingy or overprotective girlfriend
