Filling and refilling

Vacant bottles placed in racks travel in a truck. They were cleared off from the shop-keepers who sell drinks. On every jolt over the uneven road they tinkle. Like celebrating the meeting of one with another. Then a rare music is heard. The bottles sing of the tune of vacuum.

When it nears a school building, the school bell rings.
It informs the end of the day's session. Within few seconds the chorus giggles of children

after the closing bell is heard, you can listen. It resembles
the music of the vacant bottles. Peals and peals of liberated joy. Might be the bottles and the children were scheduled to undergo enforced conditioning. .From vacancy to enforced conditioning and conditioning to vacancy, the routine runs. It will be running on; making the shift of intervals delightful. One is necessary for the another.
