… Mei-Shun means not on a scale but a locker at her 2nd horsey riding club. She normally prefers even figures; 2, 6, 8, 22 while has odd 1, 5, 13, 19 as birthdays of her family members. And the latter represent upper shelves here, quite convenient to store valuables, bags and clothes. On the other paw of Mikan-chan, “1” sounds like “the best” or “top” always difficult to achieve for her mom.
