Enjoy your vacation!
Plant a garden. Read something interesting. Find new places. Climb a tree. Play in the streets. Go into the woods. Swim in a river. Run through the fields. Climb a mountain. TURN OFF YOUR DEVICES. Ignore facebook. Smash your television. Write something about anything. Hug your parents. Thank someone. Learn to sew. Meet people. Do something new. Experience life in the world.
And by all means, write Mr. D. an e-mail and tell him all about it!
