yes, they are allowed, but it really depends on the family.
it is a small time period that you and the person in your relation ship stop and think about how your relation ship is going then you decide if you want to keep your relation ship or not. it is the time to think about your relation ship basically.
The relation of man to ship is that man is the operator, controller, or captain of the ship. Man is responsible for navigating, maintaining, and managing the ship's operations and crew. Without man, the ship would be non-functional.
The relationship between the families of inlaws is similar to the relation ship with their family members. For example The relationship of my brother in law(sister's husband) and my another brother in law (wife's brother) will be simmilar to those relation ships with their brother's family.
