Is there a single word, in any language, that means what I am trying to describe in my Details?

As an example, Schadenfreude is a German word that has no real English counterpart, so we borrow it to describe when people feel gratification by other’s misfortune.

In talking about gift giving at Christmas, a friend made the following observation…That there is sort of an ideal “sweet spot” that is fun to experience at Christmas. It happens when you give a gift that you are really excited about giving, and the recipient is equally excited when they open it up and see it. There is sort of a perfect balance of satisfaction at that point-a mutual simultaneous gratification. It does not happen that often, but it is really cool when it does.

Is there a word, in any language, that describes that experience?
