We visited my in-laws over Thanksgiving. At one point, MIL was driving the four of us (MIL, FIL, The Sweetie and me). A truck tailgated us and sped by as soon as we hit a passing area. MIL said "Driving like a maniac - of course it's a truck! And probably driven by a man!"
The Sweetie said "That's a couple of interesting assumptions." MIL just started an aria about how people drive crazy on that stretch of road, and it's always trucks and always driven by men. It didn't slow her down a bit.
But at least The Sweetie and I got to exchange an amused look.
