Dear Ann Landers,
Here's a comment on your Gem of the Day, "People who live in glass houses may as well answer the doorbell. Callers know you're there." My parents, who were Dutch, owned a summer cottage on the seashore. The Dutch are very family oriented, especially when one of them owns a cottage on the seashore, and my parents were tired of uninvited drop-ins. One Sunday, when they saw a carload of people arriving, they ducked behind the sofa and didn't answer the door. The visitors, thinking no one was home, decided to have a picnic on the lawn. Since the cottage had many windows, my parents spent the entire day crouched behind the sofa. -- Arlington, Va.

Dear Arlington,
Serves 'em right. People who don't have the guts to protect their privacy deserve what they get. They should have said, "Sorry, we have plans for today. Next time you want to visit, phone, and we'll make a date."
