When the YMCA comes a calling

So while looking for a job I received a call from the YMCA about my application. I'd put that I was a Shodan in Aikido and they asked me if I'd be interested in teaching a class a week for them. I told them I couldn't rank anyone and that I wasn't willing to teach children. One of the staff there in charge of hiring has a husband that used to take Aikido which is why they called. They gave me a free pass to attend a Tuesday and Thursday class to determine if the Aikido I'd be teaching is different from their current Hapkido class. If all goes well I'd teach a mock class for the YMCA staff and then be teaching a regular class if they think it would be a nice fit. Oddly enough, I'd be teaching to earn enough money so I could attend the classes in Poulsbo. Who ever heard of a teacher teaching so he could become a student?
