Well, I can't understand why old people can fall in love each other. Do they like each other's wrinkles? Or do they like each other's hoarsen voice? Maybe this is because the old people can understand each other. Young children can play together because they understand each other and have same hobit. And elderies are same, too. They can understand each other, and have same hobby. That's why they can fall in love each other.
But, if the partner is like a crazy drivers, maybe people will oppose it. Granny's sweetheart was a grandfather who like to drive motorcycle so fast. Granny liked it, and they wanted to marry. So, this special couple make troubles between Nicholas' family!
Well, they finally get married, and this is a good ending. I still can't understnad how they can merry, but they will be happy, won't they?
