I find many things in Sweden to be rational, so why is it the case in Sweden that the person answering the phone says his or her name? I would think it would be the other way around. Presumably, especially if you are calling a mobile number, you already know who you're calling, and it should be your job as the caller to introduce yourself. (Most mobile numbers seem to be personal phones anyway, i.e. used by a single individual, except of course in the case fo snoopy signficant others who are curious why your phone is ring repeatedly at 3 am.) As the callee, it cannot be assumed that I know who is making my phone ring. When I say "hello," that greeting is followed by a question mark, as well as an implicit "With whom am I speaking?". I want to know who is on the other end of the line before I give them my name.
Gotta go. It seems I have a phone call.
