Mary Ellen and Sean
Sean had dressed nicely in a white dress shirt asnd some slacks, figuring it was okay to be semi casual. The wedding had been beautiful and he'd almost cried. Once at the reception, he looked around asnd saw Mary Ellen sitting by herself. He hadn't actually talked to her very much since arriving in the past.
"So, how's my favorite sister-in-law?" She was, at that point, his only sister-in-law, but that was beside the point.
