It is difficult to measure gratefulness. That amazing feeling you experience, after someone has gone out of their way to get you out of a bind, or to make the dark times that little brighter, is immeasurable.
I am lucky. I have a wife and parents, who unswervingly are there to help me, regardless of the situation.
Today, I am especially grateful to my little sister (and her employer), who helped us out recently. I will repay you with Roché, and jellies :)
