My daughter went to a school dance where a girl she did not know was upset and crying about an out of state friend. This girl said, "just pray that she is ok." My daughter replied, "I will pray with you right now." The girl accepted, and right there in a public school dance -- they prayed. My daughter said she was scared and it was short, but she felt led to make the word prayer mean something.
