Let me spend a day with your family. I wake up with you (or show up around when you wake up) and stay until you get the kids to bed. I'm a fly on the wall, documenting the story of your average day. I do not interfere, no moving objects out of the way, not turning the lights on/off, the only time I will step in is if the kids or family pet are in serious danger.
Half day sessions can be either morning or afternoon/evening. Depending on what memories your family wants to keep forever.
