I don't know what else to add here; that's a monkey flying a kite. It looks like the necessity to find new ways to entertain oneself during this quarantine extends beyond just humans.
Some people in the comments have tried to ruin anyone having fun by saying the monkey just happened to catch a loose string that happened to have a kite on it, and to those people I would inquire why they are the way that they are.
Sometimes — especially now — you need to just take 30 seconds and watch a monkey fly a kite and enjoy it for what it is. We don't need to debunk the mystery or do any of that nonsense. Just watch the monkey play with his kite. It's good for the soul.
