If you're seeking advice or want to express concern, here's another approach:

"I'm still trying to process what happened at the party last night. I feel really concerned about my wife's experience with all those guys around her. Can we talk about how to handle similar situations in the future?"

"Last night, I attended a party where an unexpected and uncomfortable situation occurred. My wife was surrounded by 29 guys, which made her feel extremely uneasy and overwhelmed."
