His drunk mom being "helped" by his friends.

John walked down to see his mom leaning on his friend Ben. Jen's arm was around Ben's shoulder, and Ben was 'supporting' her by her chest. Another kid named Dave was behind them, clearly groping her ass. Jen's eyes were closed and she was slurring incoherent mumbles.

"What the fuck happened?" John asked, taking them by surprise and scaring off Dave.
"Oh shit!" Ben said. "Your mom is... uh she's really drunk dude. We're just helping her to bed."
"She was fine two minutes ago when I went upstairs! She couldn't have gotten this drunk!"
"I don't know what to tell you man."
"How about the truth?!" John was clearly getting pissed.
