An Unbreakable Bond.

Grandparents have this special...what do call it...feeling / bond / magic with their grand babies.  I'm not going to pretend to explain it or understand it. And I know the feeling is mutual.  In other words, I think grandparents need their grand babies as much as the grandbaby needs his grandparent. 

So I just know that when big brother says he would rather snuggle up to Pa for a few minutes before bed time, I'm not going to argue.

Because you just don't argue with magic.
