I only voted for 1-3 because you said "close friends or acquaintances," and I'm defining acquaintances as more than just people you manage to recognize and pass a few words with when you happen to meet. I don't feel that I have any actual friends, since I define friends as people who you feel mutual affection for and who would actually choose to spend time with you if they had something else to do and didn't need something from you. The two people I'm counting are, first, a person who was my best (only) friend in high school more than 40 years ago and who I lost touch with till about two years ago when she managed to trace me on the Internet. I had tried that myself and failed. We just trade e-mail and Christmas cards at intervals of weeks, but it's still nice to have her back. In high school, she was very popular but a bit weird, and for some reason she took me under her wing. Otherwise, I wouldn't have spoken to anyone for those 4 years. The other is someone I met in group therapy several years ago. I never see or hear from her except when she wants to go to a wine festival or a powwow, which I guess none of her real friends have any interest in. She calls occasionally in between when she has something she wants to talk to someone about, like when she was going through a messy divorce, but she won't accept my invitations to visit or do anything other than the things she suggests, and we don't really have anything much in common. And that's it, after 58 years of school, work, etc., out in the world. Pretty dismal.
