There are a few things that just go with summer, and a cool glass of lemonade is one of the best.  The neighbors will be busy with their chores, and there is sure to be a big demand for the ice-cold treat that is being prepared.  Mom has set them up with the supplies, and brother has constructed their store.  The locusts will soon begin to sing their summer song.  The day will surely be a hot one.  And there will be a lot of hot, thirsty folks going by all day.  These youngsters will be here to serve them and meet the need of the moment.  They are now "Open For Business".
