Bizarre Situation

A really bizarre thing happened today.
Sam's rugby team was planning on having some sort of fund raising dinner near the end of May. I received an email a few weeks ago from a woman who said there was a "Cora's Gala" scheduled for May 22, and asked if I was willing to volunteer. I was expecting some sort of email like this, so I immediately replied and said I could help with serving the dinner. A few days later, I received another email thanking me for my assistance, and informing me of the dress code (all black), time and address. So, I jotted it down on our calendar and didn't think about it again.
Well, today is the day of what I thought to be a rugby team dinner, so I decided to double check my email for the details. I typed in the address and couldn't seem to find it. For some reason, my NZ Google Maps kept returning to New York, USA! I asked Sam to help me...lo and behold, we found Cora's Gala planned at some Poly Prep school in the United States of America!! I couldn't believe it! Apparently, I replied to a woman who sent an email to the wrong address! Talk about a mix-up!
