i was just thinking bout my nan who died last year (of unrelated causes). When she used to answer telephone, rather than say hello or wassup or whatever she would just say her own telephone number. I've never seen anyone do this before or since, and now i think bout it seems a bit psychotic. Can anyone shed some light on this? Do you do this? I just tried it when someone rung office landline, but there was just long pause + then phone went dead. They found it confusing i spose.
