Small children are like little sponges, sucking up all sorts of stuff from whatever they come in contact with.
And occasionally, that even includes learning all sorts of horrible things from their big sister.
(I'm sure I haven't seen anything yet... I'm just waiting for when 17 year old Kristina decides to teach 14 and half year old Adrianna how to drive.)
However, SOME of the things passed on from older to younger siblings are remarkably adorable.
Like playing puppies. They are ridiculously cute playing puppies together.
