On Saturday I was at a cousin's wedding. Neither bride or groom was JW, although her mother (my aunt) was JW but was DF'd for smoking way back in the early '70's and I doubt the bride (my cousin) remembers anything anymore.
Her older brother said a prayer before the dinner. It was a very beautiful prayer IMHO, and maybe he remembers a bit more of the JW experience, it started and ended like what you'd hear in a KH, but the middle was actually said from the heart and filled with love for the new couple and our family and the friends present.
I bowed my head and said Amen afterwards. I peeked across the table and saw that my mother and sister had thier heads up and did not say Amen. They could have atleast bowed their heads and said their own prayer for the couple. I thought it very disrespectful.
I know they've done this before at several other family occasions when a prayer was offered.
I think if the situation was reversed they'd be upset over this type of behaviour. It's happened when a family member didn't want to attend a funeral at a KH and they were disgusted, but my mom and sister refused to go to the church for the wedding. They only see their side/point of view, and feel their position is so superior.
