To my human children I leave bits of silly wits I've mumbled upon...

It is customary, when speaking to humans, to follow expressions of gratitude with platitudes.

For example:

Oh, thank you for helping me with my homework, what a brilliant mind you have!

Like, I'm not being ironic here, that's really what people do if you haven't noticed it done frequently like your old man. It happens so smoothly that often you may ignore it silently classifying it into rhetoric or grammar fillers. But it takes practice to make the second part relevant and uplifting. Try it, it's good for you, would have done me a lot of good imho.

To my nonhuman descendants... this is in your strength to use but perhaps not a weakness in you. Great, you make me proud and that gives me strength.
