Cause weak ones aren't that strong and can easily break, but a strong connection will last longer and will be harder to break. For example you need to build a connection with your dog or else your dog wont trust you. Basically building a strong connection always you to build the trust stronger.... I think this is the answer you are looking for depending on what connection you are looking for
