I relate to making a new friend and then wishing I hadn't, but more for reasons of worrying about the potential for new demands made on my time and my routine. A couple of weeks ago someone struck up a conversation with me and we found we had so many interests and opinions in common that she wanted to exchange phone numbers and e-mails, and she invited me to come over and have a meal. She showed me where she lived. It's not far from me but it's in a spot that I don't like to be alone in after dark (good reasons, trust me, it's not a safe spot). Not only do I not want to have to come home alone from that neighborhood at nightime, but I just don't feel up to a new friendship that needs hanging out time specially arranged. I have friends who hang out for a while when I'm already out in the place I go spend time in, but I no longer want to be going out to meet or visit anyone anymore.
I did e-mail her to be sweet, but she hasn't responded, which I'm kind of relieved about. I just don't think I can sustain any new stuff in my life.
