..When your brother is threatening to "do your boyfriends head in" for "not treating you right"?

Not REALLY a problem as they've met each other only once and would probably not recognise each other if they fell over one another in the street, but a tad alarming nontheless.

(No, I don't want him to maim him, nor do i think there are any major relationship issues to warrant such talk. People meddling SUCKS.)
