We always try to make things act the same every time. We even have genetically identical apple varieties all over instead of planting them from seed and allowing them to not be exactly the same as the parent tree.
We have a problem handling with change & differences cause everyone thinks their way is the correct way of life or doing something & their friend is doing it the wrong way. Its very hard for people of todays generation to CONFESS AND ADMIT THAT your friend/rabbi way is the correct way & your way of life or doing something specific is the wrong way.
YOU CAN’T ALWAYS BE RIGHT 24-7 (the right way for one kind of person is totally the wrong way for a different person) chanoch l’naar al pi darko
I think that many people are used to things being very routine. Seeing something different takes people by surprise, and, caught off guard, they aren’t always sure how to handle it. Oftentimes, I see people reacting to difference with fear. Folks should learn to better roll with the punches and deal with it realistically.
