A man stood up and I thought, that’s my brother-in-law Dana!
Then he turned to another angle and I thought, no, that’s my nephew Adrian!
The funny thing is, I’ve never noticed that Adrian and his father look much alike. But this stranger looked like both of them.

I’ve long enjoyed the fact that there’s an evolutionary explanation of why trees do such a good job of providing shade. The function of leaves is precisely to catch the sunlight, and any sunlight that gets through to the ground is a missed opportunity.
Natural selection helped me out in another similar way just now. I was cleaning up the hallway after a visiting upholsterer left some duck feathers on our floor. Nothing is easier, I dicovered, than vacuuming up duck feathers! A little thought reveals that this is because evolution, as it were, has optimized duck feathers precisely for vacuumability: they are designed to be as light, and as good at catching the breeze, as possible.
