Is OTHER wrong in the post ? POST : Title, I've never posted anything here but. Me and my twin brother have just turned 18, but we're both on the small side. Our parents have gone away on a trip for a few days for their anniversary so it's just us in the house.

A woman we didn't recognize called to the door and asked if our parents were home to fill out a survey. My brother told her our parents were away and we were alone for a few days.

When she left, I got annoyed and told him never to tell someone we don't know were alone, and that someone could Rob us.
He got very defensive at that, and we had a huge fight. AITA?

Tl;dr brother told a survey woman we were alone in the house, I started a fight because I thought it was irresponsible and stupid.
