Pretty much anything I like. I like my own company, prefer to cycle or walk alone for the most part as I can set my own pace, stop where I like and do my own. I prefer to travel/go on holidays alone for the same reason although I'm not anti-social and I've some of the best nights out ever during my cycle tours this year in the company of random people I met at the hostels I stayed in.
I also prefer to go to the theatre alone as I want to concentrate on the performance.
I had a lovely day today, leisurely 50 mile solo ride, stopped in a cafe for lunch, visited a beautiful waterfall I know off in a place where no-one ever goes and it was great today with all the recent rain and have relaxed all evening listening to music of many different genres and fixing my Bah Humbug tree lights.
Have a day off tomorrow so will take a solo drive to the extreme west of the county where I know I can have freebie use of a holiday cottage on the coast and I want to plan a potential cycle tour for when the days get longer in the new year and when everyone else is getting stressed with Bah Humbug shopping tomorrow I will be far from the maddening crowd.
