About the Guest
As a kid, I played a game called Lock Out. We would form a circle with linked arms and someone on the outside would try to get into the circle. The more the outsider pushed, the more the circle banded together. Sometimes stepfamilies play this game, too. An outsider stepparent or stepsibling is trying to break into the circle of insiders and find acceptance. The secret to getting inside is to not push. Instead, talk, interact, and get to know them. Eventually they will relax and let you in.
Is your family playing the game of Lock Out?
