Do you have to?

The first day of our local car boot sale started today and was well attended in the sunshine. I noticed this ,ahem, rather plump dog, imploring his owners not to buy an exercise toy for him. His pleas were ignored however but I later saw him having a half hearted chase after the toy. My only buy was a copy of The Beach so that I can itentify the beach we went to in Thailand where scenes were filmed.
