Well, that would be fine and dandy, except in the case that not everyone wants to identify themselves to potential strangers, or even worse, a (GASP!!! )…telemarketer.
My boyfriend, who has a slavic surname, answers his phone “hello”?
If he gets the “who’s this” question, he has a number of games he plays with the caller which are gently delivered, but pretty funny even so. Maybe it’s an American thing. It just strikes us as presumptous, especially if it’s asked in that arrogant, “snap, snap hurry up who are you you’re wasting my time” tone of voice.
If the caller then asks for Mr. ASdrioonuusdi???(complete butchering of said boyfriend’s surname), my boyfriend then says “no, he’s not home” and hangs up.
As for me, I don’t have my number listed, I’m a single female, if someone calls me by mistake, I don’t want some potential teen prank caller, or some perv knowing the girl’s name who has the telephone number 555-1234.
However, I’m not as quick on the draw as my boyfriend, so I usually just politely ask “who were you trying to reach” or “what number were you trying to reach”.
