Sheldon and Amy's family are good friends.
While the parents are delighted to found one another, it's another story for the two child prodigy.
Larry and his wife together with George and Mary bond over the difficulties of raising such overachieving child. They grew closer since they are neighbors. Soon, joined celebrations were held一 birthdays, graduations, holidays, and many more.
While they find their friendship comforting as they can relate to one another, it is different for the two kids.
Sheldon and Amy see each other as their rival. They are both interested in different fields of science, but their school's contests and programs could only declare one winner. It's like a contest on who can win more trophies and medals between the two.
Though, it's to everyone's surprise when one day the two came to announce they'll attend the same university and even rent a two bedroom apartment in Pasadena.
A/N: Thanks to YS, we get to see a young Sheldon get jealous and competitive with Paige. I used that storyline and Sheldon/Tam's (more likely just Sheldon's) quarrel for this. If found a story with similar plot or based a story from this prompt— I'm shamyshenanigan on IG! I'd love to read the story.
