I did & it came as a shock to everyone. The bride & groom were friends of mine but the bride's brother objected b/c he truly felt that the groom had cheated on her at his bachelor party. I don't understand why he didn't say anything earlier. The wedding was halted for about an hour but it resumed minus one brother.
I guess he had the last laugh b/c they split up a year and a half later when he cheated on her again.
