something simple, the 1.5 or so mile long walk home from school. when i'm not in a hurry (like when i really need to get home, shower, collect my tripod, camera, and auxiliary lens to go photograph a battle report), its nice to just slow down, put on some music in one ear, and just watch people as they go by, give a friendly nod to those construction workers, or really every passer-by, and feel a little more content you made someone smile just by giving them one of your own.
bonus points if its drizzling lightly, or is really any kind of overcast, and there is a nice breeze. (direct sunlight just hurts my eyes. im a big fan of complete cloud over, though its thin enough that its not darker than it should be at that time of day)
