In running a number of business's in my career, I found that any of my employees who required help in reading and comprehension of my memos, such as using bullets, were not worth reaching at all, as that inability to be able to comprehend made them recipients of cartoons or some other type of "fun" activity to help them understand.

Soon, they were simply not copied on certain memos.

Part of running a business is understanding that all are not created equal, and some need remedial help to keep up.

Just read slow and use your index finger to follow the words. Reading it aloud can help perhaps.
