I think most people plan their free time around others, as in, I want to spend time with X this weekend, so let’s figure out something we can do together. Perhaps this movie, or this concert, or a trip to wine country?
I am finding that I increasingly plan my free time in the reverse. I want to go to a particular movie, or lecture, or event, and then I have to decide if it is worth the hassle of inviting someone else.
I think the seed of this orientation was in me from the beginning. In middle school, my best friend would want me to wait for her between classes so we could walk down the hall together. I thought this was absurd– why would you need someone to accompany you down the hall? She is now married with three kids, and here I am.
