You don’t need to be a handyman to love a stopcock. You just need to be curious. Look under your sink. Find that little lever. Give it a gentle turn (but only if you know where the water goes).
You now know more about stopcocks than 99% of your friends. That makes you the coolest person at the next boring party. Use your power wisely. And maybe, just maybe, go turn one off for fun right now.
Go on. Be a water wizard.
