Most weddings I have gone to have been wonderful. As for the worse thing I've seen, I would have to say my friend M who was in the wedding party of my other friend D kept leaving the top table to go and cut her son's food up for him. The little boy was sitting at a table with his grandparents and his father, but apparently M felt she was the only one capable of doing the task.
Now, you could say she was being a good mother and I will not argue with that, but I felt that she did not need to do this with three other people capable of doing it for one meal. Also her husband, the boy's father, has shown himself to be a narcissist. He is quite cruel to my friend. So was my friend just being a good mother or was she also trying to avoid his possible cutting comments if she did not do that?
Given that I have never liked her husband, I wonder at this. At the time, it felt odd. I questioned her need to be in control versus her smoothing her husbands ire. Sometimes darkness lies beneath what we all see.... and she often felt judged by others. That is the sad thing.
For that reason, i would say this was the worse thing I ever saw at a wedding.
PS this boy is now 18 and he and his younger brother have joined their father in the belittlement of their mother who is the sole financial supporter of the family.
