Awsaj's Windy Day

It is a windy day at our Awsaj school. Ali holds an open bottle and throws it into a bin, but two bottles fall on the ground. Sara closes the classroom door to keep cool air inside. At the entrance, the dust mat is folded, so dust blows in with the wind. Near the canteen, a tap leaks drop by drop. A refill station is working, and three students refill their bottles.
