What I learned how to do yesterday

Drill holes in concrete so I could hang this: 

Drilling holes in concrete required learning about masonry bits and how to distinguish them from normal drill bits while sifting through our ever-growing collection of various bits and learning about the hammer drill setting on my father's ancient but most powerful drill. 

This is what I do on the weekend when my father and boyfriend both go out of town.  The shelf is beautiful, and I'm so proud!
