Those tricky silent letters

Me: What did you learn about in school today?
El: Did you know it's black history month?
Me: I did. Did you talk about some famous black Americans?
El: A little. But then I got to read this book about Rosa Parks. She did not want to stand in the bus assel just because she was black, but black people had to stand in the assels back then if white people wanted to sit in the seats.
Me: Oh, sweetie, the "s" is silent. The word is pronounced EYE-ull (aisle.)

'Cause standing in the aisle's bad enough. Hate to think of what it's like standing in the bus's assel.
