Why is Rose of Sharon frightened of the religious woman?

Lisbeth Sandry, a religious zealot, speaks with Rose of Sharon about the alleged sin that goes on during the dances, and complains about people putting on stage plays, which she calls Œsin and delusion and devil stuff.' The woman even blames playacting for a mother dropping her child. Rose of Sharon becomes frightened upon hearing this, fearing that she will drop her child.
