I am struggling with a dilemma that I hope some of you can offer advice on. As some of you know from other posts, I have been on a walking program for the past three months or so, increasing my daily walk from 5 to 40 minutes during that time. I would have to say that it has been one of the key elements in my ongoing recovery, and has turned into one source of joy in my life. The other day, I invited my next door neighbor (I live in an apartment building) to accompany me on my walk. I know she likes to walk and she is retired now (I am on summer break) and has time, and I thought it would be fun to have a companion. It was fine, and afterward I said I enjoyed it and she should just knock on my door any time she felt like coming on my walk again. She knows what time I usually go and where I go. Well, I didn't expect this but the very next day (yesterday) as I was getting a drink at Starbucks for my walk (part of my routine), she shows up in her walking outfit! She says she heard my door slam around 4 and knew I was going on my walk and thought she'd head me off at Starbucks. The walk was ok but definitely not joyful, and now I am sort of regretting my invitation. I value my alone time during my walk and don't really want a walking partner EVERY DAY. Now I don't know what to do. I don't want to lie to her, change my routine, or evade her, but I'm not sure how to let her know kindly that I really don't want a walking companion every single day. Help! What would you do?
