It's not weird for an adult to go on the swings.
Anyone of any age can play on the swings as long as the swing is built to handle your weight.
Most swings at parks are built to handle an adults weight easily.
I just actually bought myself a swing seat that has a strong chain on it that I'm gonna hang on a tree in my yard and play on it this summer.
I loved swings so much as an adult and I don't care what anyone thinks.
Being an adult can suck and playing on the swings is a good way to go back to your childhood and have fun and get some exercise at the same time.
It's perfectly fine to go to the park and play on the swings as an adult.
We all pay taxes for the park and you are entitled to play on the swings as well.
Have fun as we all are gonna die eventually and we should have fun while we're alive.
If swinging on the swings or going down the slides etc are fun to you then you should do those things and have fun.
Don't worry about what others think of you.
Some people might think it's weird but that is their problem.
