guys, guys, guys, the parents must act mature for the kids for one night, they are small children, the enjoy having their parents with them for trick or treating, how long could they be out for? a couple of hours? I'm sure that dsh can handle being in his wife's presence for that amount of time and considering they're out with the kids, I'm pretty sure they'll be focused on their kid's halloween experience: taking pics, video, encouraging them, checking what kind of candy they rec'd, etc.
Part of db'ing is being an adult about situations, we don't need to segregate occasions like halloween when the kids are so small.
