I bumped this thread to tell you a story. We had a meeting of our environmental group last week. One of the fellows who works in the office where we met had his seven year old daughter with him, a cute little blonde girl named Violet, who was wearing glasses and jumping around, full of energy. All of a sudden, she splits her fingers in a V (like Spock) and says to us, "Live Long and Prosper." She seems to have selected this as an all purpose greeting, good for all occasions. I told her her hand symbol was also the secret vegan hand signal. She also got to meet the president of our group, John, a vegan.
