Write a thank you?
The building where I work is in the historic district. Some neighborhood homeowners organized a garden tour of six local homes. They sent invitations to buildings that belong to the historic society, so an invitation came to my office. It requested advance payment of $5. I sent in $10 for a friend and myself. We went to the informal, self-guided tour of gardens, then enjoyed a one-hour garden party on the lawn of one home. There were a few people in attendance we knew (it's a small town). A variety of pretty tea sandwiches, small sweets, lemonade and tea were served, and it was all quite lovely, with recorded music, a hired server, white tablecloths on a small canopied buffet table, etc. We thanked the host and hostess, people we had not known, and admired their gardens. Should we send thank you notes for an event like this?
