On a rainy evening, John comes home from work reeking of fish and with his hair coated in grease. He sees Dad and Harry in the kitchen and mutters a hello before plodding off to the shower.
Dad calls after him, "John, when you're finished washing up, come out here. Your sister wants to tell you something."
The teen grumbles his assent. He's exhausted from working all day, he's got a hundred stoichiometry problems to do by Monday, and he really needs to get something done before bed. (This had better be important.)
Once showered and changed into fresh clothes, he joins Dad and Harry in the kitchen. "So, er, what's going on?"
"I'm going to quit drinking. I went to an AA meeting with Mum today, and while you were at work, I poured out all the beer in our refrigerator," Harry says, nodding towards the full rubbish bin.
Grinning broadly, John tells Harry he's proud. His greatest fear is that her sobriety won't last.
