At my wedding last weekend, an old friend who I don't see very often now got VERY drunk. He insulted several of my family members, broke a wine glass on purpose, and actually kicked my husband in the butt (which he barely felt since the guy was too drunk to hurt anything). Then he was escorted out by some tall family members.
He has a history of being an obnoxious drunk, but the last few times I've seen him, he's been fine; and even during those obnoxious drunk times, he's always been nice to me. If I thought that he'd be a problem, I wouldn't have invited him. His girlfriend, who is usually a calming influence on him, apologized profusely (and it was when she was trying to get him out of there that he said inappropriate things and kicked my husband). He hasn't apologized and I don't know if he will.
So. They gave us a wedding gift. How do I write the thank you note?
