In her spare time, Sarah's been building magnificent creations with Duplo Lego blocks.  We have some special parts that she uses to create tube slides for the Duplo people.  Yesterday while her siblings were napping, she built a giant swimming pool with three water slides.  Right next door there was a raspberry patch and and ice cream stand.  She demonstrated all the parts of the creation for me, and then proceeded to tell me that the admission for the swimming pool was a mere $2.  For just one extra dollar, you could pick two buckets of raspberries in the raspberry patch after you were done swimming, and then saunter up to the ice cream stand to have a chilly treat.  She said there were hundreds of Duplo people who visit the swimming pool daily because, "the prices are just so reasonable. . . if real swimming pools understood reasonable prices, and built a raspberry patch next door, they'd have so much more business."
