Headmistress stood up at start of play and asked that young children be brought outside if they became disruptive to the children on stage. She also said no videoing or photographing during the performance. A school video would be made and sold for £2 which would go towards play equipment, and parents could take a group photograph at the end of the play.
We still had toddlers running around and making noise, parents standing up and blocking people's views while they took photographs, not to mention the mother who answered her phone during the play.
Yes, I know it's not the RSC, but why can a bunch of adults not do as they're asked for 20-30 minutes?
