My SIL and her husband are invited to a wedding. My SIL desperately wants to go, but her husband does not want to go. SIL does not want to go alone, she is not sure she will know anyone else there. My SIL wants me to go with her in her husbands place. I do know the bride, through my SIL, but have not seen her in many years.
Is it OK to go as a substitute guest?
