Catch the money from going down the drain!

Take a pitcher, old milk gallon or even watering pot that you don’t normally use and place it by any sink or shower. While you are running the faucet and waiting for it to warm up to a certain temperature, use the container you’ve placed by the sink or shower to collect the water that is too cold and would end up running down the drain. Use that water to water plants or use it for something else.
