People learning English often say that prepositions are tricky. Using 'at' instead of 'on' can completely undermine your argument or turn your aside into an attack. You have to memorize idioms. There's no way around it.
For instance, today I accidentally typed Burn Without Reading when writing about the Coen movie. A number of writers have joked about the actual title of the movie being applicable to the film itself (guilty), but I think "without" might've invited even more of it.
A few alternate titles:
- Burn despite Reading
- Book-lovers Burn about Reading
- Arsonists in Berkshire: Burn in Reading
- And my favorite: Burn by Reading. Zap!
