Let's say a group of people are sitting in a room. On Shabbat, are you allowed to categorize them into groups such as:
- Herding Men away from woman e.g at a Kiddush with a mechitza in Shul (normally that Shul doesn't segregate during Kiddushim)
- Separating a group of children into teams e.g for Shabbat groups / games
- If one has to physically carry inorder to fulfil borer, separating toddlers into age groups e.g for food consumption purposes (some are too young to eat certain foods)
