On July 13, 2268, Amata Almodovar brings four hats to Vault 101's cafeteria in anticipation of her friend's tenth birthday party. During the party, the Lone Wanderer can wear the kid's party hat. If the Lone Wanderer speaks with Wally Mack, he will express his scorn for the party, pointedly singling out that kid's party hats and balloons are for younger kids. (Interestingly, Wally himself is younger than the Lone Wanderer, thus making his bullying insult somewhat lame.)
