people who share too much?

He asked how it was going, and I replied that things were okay, I couldn't stop sneezing, and maybe allergies were the problem. I asked "how are you" reciprocally, and he started to tell me about his father's poor health, being in and out of the hospital several times to avoid death, paperwork, notes from doctors, dealing with employers, medicare, disability, jury summons, moving, mailing addresses that banks and other organizations had that needed to be changed.

All this via instant message, initiated by him, the first time we had talked in almost 2 years. It's not that I don't care (at least I don't think it is), but to dump all that on someone who you were never particularly close to in the first place and after a few seconds in online chat? I guess I just don't feel comfortable with that level of sharing.
