Once when I was flying gliders I didn’t feel “flying alone” really some sort of waste. Well in fact, the more interesting gliders were single seaters. And often, when the weather was good, some day during the week, it was hard to find anyone to fly a whole day with you. And also flying with two or more gliders instead of sitting in the same cabin was also quite nice. So I have quite many hours flying alone, only listening to the air flow and watching … 
Now I bought my plane because I never fly alone. I have several two-seaters at hand for free, but they’re not enough. I had up to 6 pax in my cabin (all within legal limits) and I only fly alone after maintenance or when I have to check something. Mostly four or more. Lastly we did lots of IR training, that was only 2 to 4 POB. 
I would like to go alone again some day
