There is an adage that says you can't have your cake and eat it too. But I take issue with that. 

Benjamin enjoys the time he spends with people he loves not just twice, but thrice. He counts the planned activities on his fingers that are in his future, and grins. He does this while pacing, because the energy requires movement. Then on the appointed day he shows up with a hug for those friends, and is fully present. Well, as present as someone who compulsively reports these joys to his siblings on messenger can be. Then, when the dust has settled, he counts his week's blessings out loud to me. 

"I saw my friend on Monday at the cathedral, on Friday for Meals on Wheels, Sunday at church and a walk, and Monday for a Horizons event!" He can hardly contain his good luck. 

But the miracle is, there is no need to contain it. Letting it spill out is a way to immerse himself in it. 

He does the same thing not with cake but with cookies. He buys them, with money he earns cleaning for others, and keeps them at his desk. Then, when I have a sewing student, he joyfully offers them treats. In the case of big goodies, maybe one, with smaller varieties he gives several. Later that day, he will tell his brother about the burst of generosity, and feel good all over again. 

It seems to me to be a source of sweetness that has nothing to do with actual calories.
