What do you do for fun? And, is it better if you share it with others?
Most of my hobbies can be enjoyed alone but I much prefer sharing the experience. A good book that needs a lively discussion, the movie that everyone liked for different reasons, the soup or sauce pot that needs more spice and some stirring, the walk where you all spot the young buck or bird at the same time, and the opening of a bottle of wine where each person smells or tastes something different.
The Chinese have an ancient philosophy of guanxi which has to do with relationships and caring for one another. They believe that shared experiences enhance lives.
Give it a try. Make a meal together, watch a movie, take a walk and remember to savor life.
