A Spray Botttle

It's production time in school. Choir, drama, (eating) dance, scenery, props, (more eating) costumes, rehearsals...it's what everyone is busy with.
On Tuesday, Chava Goldbaum was told by the props committee to bring in a spray bottle for her prop.
That night Chava found in her house a spray bottle that was almost empty. She got permission from her mother and brought the spray bottle the following day.
Wednesday, sitting in class, Shiri, a classmate of Chava's accidentally knocked her desk and her White-Out spilled all over the carpeted floor. Wanting to help clean the mess Chava looked at her spray bottle she brought in. Smiling she walked over to spray the spot. The bottle that she 'happened' to bring in was a carpet cleaner spray. She cleaned it up until there was no trace of White- Out left.
