I like to think of people as being aware or not aware of something.
When a person is born, they are not aware of much. They then start becoming aware of things such as their senses and information. Given the amount of general and detailed information available to become aware of on earth, people are often unaware of most things (relative to all things).
Becoming aware can be a factor of age, situation, geography or interest, amongst other routes. For example, most people won’t become aware of the idea of 8 x 8 until they are about 7 years old. The majority of people won’t be aware of the daily routine of a type 1 diabetic, unless they become one, or are very close to someone who has. Additionally, if you grew up in England, especially as a fan of football, you would probably be aware of the significance of 1966. If you grew up in Canada, and followed baseball, probably much less so.
Generally speaking you can become aware of anything, either intentionally or not. But with so many millions of pieces of information available to be aware of, and millions more created every day, we should go a little easy on people who are not aware of the things that we are. Just because a person doesn’t know something about a topic dear to you, doesn’t make them wholly uneducated or ignorant. They are simply unaware of that particular thing.
For today, try not to judge people based on what they are aware of, but rather, kindly and pleasantly, make them aware of the information you feel is important and assess their response to it.
