Rules from a father you have to comply with before marrying his daughter.

We are all humans, and thus, we are imperfect. This imperfection also
manifests in the areas of keeping rules. Rules like these are no

The man who put up these milestones have to be asked to prove beyond

before he can be qualified to give it out to his future son-in-law!
