13 brooke: mr. torres, i have an idea. we just completed a unit about green plants and photosynthesis, so perhaps our class could volunteer to create the garden for some hands-on learning
14 marty. brooke, that's a fantastic idea. i would gladly donate a day for an outdoor excursion.(with a snicker) it sounds better than algebra
15 mr torres: well-(hesitating) i suppose some real-world experience with plants and sunlight would be very informational-and fun! we'll have to take a vote to ensure that everyone supports the idea. all those in favor
