I think everyone has missed the really significant thing here – that the OP will get to hold this over his little brother for the rest of their lives. Wild, teenage party stories are great dirt to rehash at any festive occasion; hours of fun!
I was the responsible older brother who didn’t get into trouble (as far as my family knew), and my brother was the irresponsible troublemaker. Also, more popular.
My parents were going out of town to visit relatives one weekend, and called me at college and suggested my brother “might be lonely his first weekend on his own,” and maybe I should visit. Naïvely, I did so… and arrived home to find The Mother Of All Parties going on. The subdivision was packed with misparked cars, from one end to the other. On entering my booming house, some tartlet with blue eyeshadow to her temples and really big hair (this was the '80s), informed me it was a “private party,” and that I wasn’t invited. As our poor little doggy ran up then, seeking sanctuary, I grinned and informed her “oh, I think the party’s over.”
I found my brother, worked out a brotherly agreement – I wouldn’t snitch, he’d have a couple hours to bring everything under control, it would be over when I got back, and I’d leave before mom & dad got home that weekend so he could explain however he wanted. The dog and I vamoosed, he kicked out the chaos, and by the time I got back there were only beer bottles as far as the eye could see, and the sour smells left by teenagers who couldn’t hold their liquer.
I’m still hazy on the details of how he explained the stained rugs, the hole in the wall, etc. to my parents. But since I’m the older brother, I revel in bringing out that old chestnut at every opportunity. Such as at family reunions, or his marriage. He’s a lawyer now,* with two kids, and I’ve already told him that the first time he overreacts to my nephews when they reach teenaged stupid, The Mother Of All Parties story will be polished off and paraded around for the amusement of all.
- I don’t even have to make the “well, he was familiar with the legal system” jokes. His friends usually beat me to 'em. Damn (mid-30s) rugrats.
