If you have kids or even more than a few adults living in your home, I'm sure you've noticed at the end of the day, half-empty cups and glasses of water sitting around the house. Once in a while you'll get the odd, responsible person who actually takes the glass to the counter and empties it or better, saves it for later. For the rest of us, it's a daily or every-other-daily chore to walk around the house picking up what everyone else leaves behind.I've made it a habit to set aside the tallest cup or glass and pour all the other water into it. I then take that and water the house plants! Not only does this save a little tap water but it reminds me to actually water the plants. With news of water rates going up this summer, every little bit helps!
