Games, brownies, chips and soda pop in the back yard. Little kids on the swing set, or kicking the soccer ball across the lawn. Listening to the neighbors' sprinklers come on as the sun sinks. Cool breezes, back-porch lights.
(I just hope somebody comes. Poor DH has been on the phone the whole dang week trying to drum up partyers. If you're in central Cal and belong to an elders' quorum ... any elders' quorum ... come on over, we'll take ya.)
