I hear a lot of people saying that. Interesting, however, is that I, as European, don't even think twice about it[1]. My brain must be wired to look at the context primarily.
Why that is, I can only take a stab at: I guess we see a lot more from you guys on the other side of the pond than you see from us. :)
