6 year unknown grudge

So, my cousin invited me via my aunt to a party for another aunt. Then, when I checked up today for confirmation of the details, she told me 6 years ago she lost $20 when I was around her house. Though, I don't actually ever remember going to her house. Especially during the time I was working at least 3 jobs and teaching full time.

It humors me to the point that I won't bring it up that $20 is grudge worthy. I've had cars, every movie, and definitely more money taken, but a grudge takes a lot more from me.

As these things go, you can't just deny it and call it a day. So, as I know she is trying to be nice to her mum on that day, I'll simply plan to visit her mum the day before, and count my class I'm teaching as reason not to be able to make it. I'll then be able to see her in November for my grandma's 80th birthday party.
