Basically, if I care about you, I have at some point or another thought that I upset you with something I have said or done, or perhaps with something I failed to say or do. Such is the manifestation of my pathos. I often feel the need to apologize for things that probably have no life outside of my own self-recriminations, and I really need to get out of the habit of using friends as unwitting mirrors of my insecurity.
I'm going to try not being quite so hyper-aware of my "negative" effects in your lives. I don't anticipate that I'll change much outside of my perception, but in order to make this work, I've got to ask a favor... In the event that I do upset you, please just let me know. Be honest. I can take it.
