I was on vacation last week, lying at the pool with my sister and our husbands. My sister took a picture with her phone and posted it on Facebook. I, too, was on Facebook, saw the picture, and “liked” it not ten seconds after she had taken it. She looked at me and said, “Did you seriously just ‘like’ my picture instead of turning your head and telling me in person that you like it?” (After all, we were lying only a foot away from each other.)
