I finally did my 2 lists. When I did this Dare previously, I on his behavior before his affair. However, this time, I decided to be 'true' to the Love Dare and do it based on his current behavior.
This time, the 'positive' list was very hard to write; the negative was very easy to write. Picking a characteristic from the positive list was hard (since it was so SHORT), but since I had been thinking for a few days about what to write, I was fortunate that an opportunity arose to give him a compliment.
