What "best day" stories are related from the characters during Alaska's game of Best Day/Worst Day in "two days before"?

In the Best Day round, the stories are, for Miles, THIS day, Alaska's trip to the zoo with her mother when she was eight, Lara being the interpreter when her family moved to America (because she was the only one who spoke English), and Takumi's losing his virginity. For Chip, the best day is in the future, when he can buy his mother a house.
