kitty, could she be a secret phone hater, someone who prefers phones to be used only for "conversations of purpose" rather than for chatting?
I am but in my case it took extreme determination, when I felt my mother was being too nosy and phoning too often, to implement my preference. And very few people understand. They just think you're being a recluse or rude or both.
I have yet to work out what's actually wrong with being a recluse but the idea was thrown at me like an accusation. The fact that I do get out and see people seems to be irrelevant.
Anyway, that was part of the reason I suggested postcards if things continue as they are right now.
