We have triggers that some times make people come out automatically, but most of the time it's who ever wants to be out comes out.
I am usually always out while on the college campus and in class and in counseling, the teens come out when they want to watch a good movie or tv show, the little ones come out to watch their movies or spend time with the pets, etc.
Most of the time the younger kids come out when we're at home, but some of the teen/adults come out for the responsible stuff (like homework).
