Knowledge: The first 2 AA in AAA is American Automobile, which makes sense as it is located in the USA and is a car insurance brand. On the other hand, Alcoholics Anonymous is an organization to help alcoholics to stay sober.

Conversation:
I don't like alcohol. I have never drank it!
Interesting. The state of not having a measurable effect from alcohol is called sobriety.
I see, is it the same as a sobriety test done by law enforcement?
I couldn't tell you. However, a person in the state of sobriety is called sober.
Yes that makes sense. Do you know about AA?

Response: Yeah I heard AA is an organization to help alcoholics to stay sober.
