Today I went walking along the Panama City coastline and skyline with 3 friends. Stopping to take a group photo, we picked up another traveler, Miranda. A few minutes later, each was finding himself on my Facebook. (I had a cellular data connection to make it easier for some of us to meet up.) So Miranda finds herself to invite herself to friend me and says “We have a friend in common.” I ask who. She checks. It is my friend Carola, with whom I remain in touch. We never would have realized this. Pretty cool.
