Our friend Emily was throwing a black and white halloween party, so Derek and I spent a few weeks trying to think of the perfect costumes to wear to it. We went through all the costumes that we thought were obvious - salt and pepper, newspapers, jailbirds, etc until we decided to try to go as coal and diamonds. However, the morning of the party, Derek had a much better idea:
Each one of us dressed as a certain element from the periodic table (C = carbon)
Which means that when the two of us walked around holding hands, we were carbon dating.
Derek kept calling me his little radioactive isotope all day long. My parents would be so proud.
