Taking long relaxing walks or bikerides and enjoying solitude
Playing videogames solo
Chatting and/or playing videogames with online friends
Visiting friends or meeting them at pubs
(Usually do this with my GF, but once or twice a month i go solo, my friends usually do the same. Boy's night out so to speak. My GF is ok with it as it is usually on a 'raid night' so she's busy anyway.)
Reading books
Listening to rock/metal music
Fixing computers for family/friends, or for strangers at a small charge.
Suddenly it feels like im on a online dating website. You're a nice lady lahnnabell, but the USA is a bit far away.
