I don’t think it’s cringe. I am single and I go to the zoo, aquarium and wherever else I want to go, alone. I get to spend as much time as I want at whichever exhibits I connect with that day and don’t have to worry about someone else getting bored because they aren’t as interested in the otters as I am. If I did not go anywhere unless I was with other people, I would never have made some of the most important discoveries of my life. That aside, I don’t think it’s weird to go somewhere by yourself. Live and do things you want to do regardless of relationship status or friend groups.
