Past XML's "XML and Cheetos become friends as kids" lore:

On past day before they become fully grown up, XML was playing on playground at Kindergarten, XML swinging on the swing... then XML stopped swinging before XML saws Cheetos was being bullied by random kid. XML gets off the swing then XML runs to them... XML gets in front of random kid's way and said "Please don't bullin' him!" ...After XML said that, XML blocks random kid's way to prevent him from bulling Cheetos... Random Kid said "Ugh. You ruined fun...", he walks away. Before random kid continues walks away and said "If you ruined it again... You're next then" then random kid continues walks away. XML looks back at Cheetos and said "Are you okay, Cheetos?", XML holds his hand out to Cheetos. Cheetos surprised looks at XML's hand then happy looks at XML and said "Yeah". Cheetos grabbed XML's hand then XML helps Cheetos up. XML said "You were got bullied..." and Cheetos said "Yeah... I don't have any friends as well...". XML sad looks at Cheetos and said "Awww! Are you lonely?" then XML suddenly sad went to happy because XML had idea. XML said "Hey!" and Cheetos confusedly looks at XML. XML said "I can be your friend!" and Cheetos surprisedly looks at XML. XML said "My name is XML!" then Cheetos smiles and said "I'm Cheetos..."
