Is there a game that either your family or your CB’s family enjoys playing? Play a game with them! Monopoly, Risk, UpWords, Rummycube, Settlers of Catan, and Nuts are some games my family enjoys, and there are endless other possibilities. Remember to ask about house rules ahead of time, often different families play games different ways.
A fun twist to this would be to have a “family game night” and have both families get together for an evening of fun.
