A few weeks ago, my sister and I took our sons for a walk, including a stop at the hardware store so she could get her mower blade sharpened. We made sure to instruct the boys to stay away from the sharp blade, and were careful to keep it out of their reach. I somehow forgot to apply this logic to me. Absorbed in a riveting story she was telling me, I forgot my sister was carrying a mower blade, and that she likes to talk with her hands. Suddenly, I see something metallic under my nose and go past my ear, missing me by about 3 inches. Always make sure hands-talkers aren't holding anything before starting a conversation!
Another stupid thing I've done - I was ironing, and bumped the ironing board. The iron started to fall to the hard tile floor. I didn't want either it or the tile to break, so I grabbed the iron mid-fall. Just not by the cool handle. Ow.
