How to make someone happy for very little cost/effort...take away something that they're used to having and take for granted...and then give it back to them!

I thought I had lost my wedding ring, especially after Aaron, the best finder of things in this house, tore the house up and down and could not find it. We were contemplating driving all the way up to kung fu to see if I had left it there...when I found it under the coaster on the windowsill of our bedroom. I literally cried.
