They do. I don't.

My older brother got married this weekend.
The ceremony and reception went off without a hitch, minimal family insanity, and a good time was had by all.

My mother was very worried about her prominent role in the ceremony. But after extensive coaching and visualization exercises (see picture) she successfully lit the candle on the altar.

The highlights of the wedding weekend were as follows:

Rehearsal Dinner - My dad stood up to make a toast. He opened his speech by saying, "Eva and I are happy that you all could be here to celebrate the wedding of David and Jennifer."
The whole room roared with laughter.

Reception - The best man delivered a hilarious toast and presented the bride and groom with his wedding gift to them. Custom bobble-head dolls. He said that the dolls could be used to re-enact the wedding ceremony for years to come and nod their heads as they said, "I do."
