people who watch Wimbledon

My sisters Mary and Joan are tennis fans, and Mary's visit with us happens to coincide with the Wimbledon championship, so our TV has been tuned to ESPN daytimes this week for the matches live from London. This morning we watched Serena Williams win the women's title, and tomorrow morning we will be having breakfast while we watch the men's title match (Federer vs. Murray)... One good thing: there aren't many commercials, but what's funny is that most of the ads are for Rolex watches and Mercedes-Benz. What does that say about the tennis audience? Might we be the only ones who don't belong to a country club?
