They are best friends, Michael loving making Sarah laugh. He says it has always been easy and rewarding. Sarah loving that he can still make her laugh until she can't breathe. I have heard it said that the shortest distance between two people is laughter.
Michael chose the three stone setting of Sarah's engagement ring to represent their past, present, and future. And I trust that they will have as wonderful a future together as has been their past, and certainly by these smiles, you can tell their present is a delight for them both.
