Friends are a terrible thing to waste

I have a friend who is concerned that I don't "tell her more" about myself...my day to day activites...my inner most innerds. When I think about it I wonder...what does she really want to know? I mean, I find life outside of myself much more exciting most of the time. Is it really that I don't talk enough (whatever that means) or is it her own insecurity that she feels she's talking too much. I suppose I could psychoanalyze the whole thing, but that would only lead me down a road best left alone.
