A friend said, of a good-looking older woman: You make this aging thing look good.
A friend said that many older people remember the answers they learned as youngsters but nobody asks those questions anymore.
The 2nd graders had a sheet with five parallel boxes. The first contained 3 circles and the next had 6 circles. The directions said to continue the pattern and the teacher's answer sheet said it could be doubling: 12, 24, 48. It also said it could be added 3: 9, 12, 15. The kids wrote 3,6,3, alternating between 3 and 6. I think they are smarter than the authors.
