I have become in the store boxes stage and have at least 2 but preferable 3 or 4 boxes of the same couple before I open them just to have a bigger chance to have a new generation boy and girl.
and learned to push away my curious nature and to not open any boxes before I'm absolutely sure I likely will have a couple.
I have been disappointed to much why there is in my opinion no other choice.
