I seem to be unusual for crafting an avatar that actually looks like me.
Back on-topic, I've been using Dizzy's "auto-lateral" phone hack in lieu of Pescado's, and it's surprising how much it relieves phone annoyance.  I think the stupid "Is so-and-so available?" popups were half the problem.  They interrupted gameplay.  Now I get those "why haven't you called?" nags, but they're no more annoying than the "so-and-so isn't a friend" warnings because I needn't click on them.

I just mentioned this mod on another thread.  Since installing it, I haven't had a single "Why haven't you called?" call.  The only calls I get now are to invite my Sim out or to have a quick chat.  Maybe it's somehow stopping them coming through, because I don't think it's a feature of the mod - anyway, whatever it is, it's very welcome.  Those calls were driving me crazy.
