Your brother goes to the refreshment stand to buy all of you a hot dog and a soda. After everyone finishes eating, one of your brother's friends throws his cup under the bleachers. You and several friends bring your lunch to school and quickly go to your favorite table to eat lunch. For the past several days, the group that has eaten lunch at your table before you has left one or two items on the table or on the floor under it. You and your friends have picked up the trash for them.
Today there is a lot of trash on the table and more under it.
You go with your friend's family to a picnic at the local park. After lunch, everyone leaves the paper plates and leftovers on the table and goes for a hike around the lake. When you come back, the wind has blown everything off the table onto the ground. Your friend and his family start packing up the food and extra drinks, leaving the trash on the ground. You and several friends are spending the day at a local amusement park.
