My fiance and I are hesitant about what to do for a FG/RB. I have two little half brothers of the same age but both are WAY too hyper to have as RB, one more so than the other. I really dont want to pick one and have the other get upset. And for a FG neither of us have female siblings or other family (or children of friends even) that are old enough to be a FG. Would it be weird to not have a RB or FG?
