They are so boring! Everything just the same: the same food, the same customs, the same music, and the same elaborate overdone make-up. It is like watching the same movie again and again, only, with different casts. There are no surprises, nothing memorable.
Most people can't recognise their individuality, so they fail to give a novel touch to these functions. They merely copy each other. They pick up pieces of various wedding styles from the internet and stitch them together. But they forget the most important thing: individuality.
Whenever our attention is fixed outside, whenever we want to look like someone, dress up like someone, behave like someone, we kill our individuality. We turn into copycats.
