禮貌，并不需要花錢。用完馬桶后，把馬桶蓋放下；上電梯時，耐心等別人出來再進(jìn)去；把購物車放回指定區(qū)域；在借東西時，歸還時要東西的狀態(tài)要比你借的時候還要好（例如給車加滿油、把物品清理干凈）。
Courtesy costs nothing. Lower the toilet seat after use. Let the people in the elevator exit before you enter. Return shopping carts to their designated areas. When you borrow something， return it better shape (filled up， cleaned) than when you got it.
"Never let your fear decide your future."
