You’re driving down the road and see one of your favorite signs: “Free.” There’s a couch, a bookcase or a desk that you are sure would look great in your apartment… until you get it home and realize it’s about a foot too long to even get through the front door.
You didn’t have a measuring tape with you, but you did have a handy ruler with you all along. Measure your hand and use it as a ruler when you don’t have one, you know, “handy.”
You can also measure your feet, or the distance from your elbow to your fingertips, for those times when you need to measure something. Of course, you could always keep a measuring tape in your glove box, too!
