BSA ka Jhagda: Section 29 ko kaise samajhna

Maine koshish ki hai BSA ki sections ko samajhna, lekin Section 29 koi bhi sense nahi deta. Yadi 2 vahi persons ek saath hain to unka koi direct interaction to nahi hona chahiye? Lekin Section 29 kehte hain koi bhi direct interaction to bura nahi lagta. Bas yeh karna chahiye ki 2 persons ke beech koi third person ko include karo, toh yeh direct interaction ho jaata hai. Lekin kya yeh Third Party Rule hai? Maine socha tha koi naya concept hai, lekin ab tak kuch samajh nahin paya. Koi bhai kheench sakta hai iska aasan explanation?
