you can't tell a baby boy apart from a baby girl if they are dressed in the same clothing of the same colors.
this often happens at the other end of life and time.
this summer, i was driving west on kessler boulevard on the northeast side of indianapolis. i was behind a person who was going slowly and pokingly about 15 miles below the speed limit.
i passed the driver. i thought it was an old woman, because i could see gray hair. but when i looked into the car, i found that it was an old man.
