The subject isn't important, but the together time is. You know your family's interests and style best, so choose an activity that will pique everyone's curiosity. Sign up for a seminar, nature walk, museum tour or other instructional outing. From visiting the zoo to exploring a model train museum, sharing an experience the whole family can enjoy will provide a focus for the excursion and offer lots of topics to talk and laugh about later. If you're on a budget, many community activities are offered free of charge or for a nominal fee.
