It's very American behaviour - like all the bumper stickers on your cars, and signs on front lawns declaringing "Our son Ethan is a Tight End on the Highland Park Scots Football Team!", "Becky is a Cheeerleader - Go Tigers!"
it's weird to us, but it's your culture so we respect it.
Same with that truck: we'd never ever do it, but you go right ahead. Just don't park it in oour neighbourhood, thanks.
