Ms. Gonzalez: Tomorrow is our trip to the nature center. The bus leaves at eight o'clock sharp, so be in this classroom by seven forty-five. Wear closed-toe shoes, because we'll be hiking on rocky trails. You won't need any money, since lunch will be provided, but please bring a full water bottle. And remember, if your permission slip isn't signed, you'll have to spend the day in the library with another class.
