I have screenshots of this somewhere, but it was many realtime years ago. An adopted sim who somehow grew up to look just like my RL best friend (I may or may not have had a hand in making that happen, but I mean the traits matched so why not) had his birthday from Teen to YA on the same day that a Child in the household aged up to Teen, so it was a dual celebration. But it was his cake that set the house on fire. I wasn't worried because I knew that I was never going to let anything truly horrible happen to one of my households and if all else failed I could just quit without saving and try this all again.
Anyway, so the birthday boy/now YA is sitting there happily eating his cake and staring blissfully into space (it was a chocolate one after all) while the rest of the household was yelling, screaming at the fire, running in little circles flapping their arms about, until the fire brigade showed up. The thing is, to hear him describe it this is
exactly how my best friend's real life 16th birthday went so many years ago, before we ever met. There was no fire, but he was the youngest of six and all of the older members of the household were yelling, screaming, arguing about some nonsense or other while he just sat there happily eating his cake, staring into space, doing his best to ignore all the nonsense just for the sake of sanity.
Spooky!
