A couple of questions:
Do Brits use the saying about a man not buying the cow if he can get the milk for free? How about "until the cows come home"? I know both of those are pretty common here in Texas, but this is Cow Country. *shrug*
Also, I'm a little unclear about the usage of y-fronts versus briefs. Is y-fronts just an old-fashioned term (i.e., more likely to be used in the Marauders' teen years) and the same undergarments are more likely to be called briefs today, or do the two terms describe different types of pants?
