No...I'm not from Nova Scotia

My husband and I occasionally rent a car to get around; living in the large metropolis that we live in, it's very expensive and slightly illogical to own a vehicle. Nonetheless, it's Thanksgiving weekend, so we rented a car to travel to my family's home a few cities away.
Renting a car has a lot of inherent issues. You basically have a set of vehicles to choose from, and you drive away with it subject to a whole bunch of rules. We occasionally get vehicles registered from other provinces, and even from the United States! Today we got our Nova Scotia plated SUV on the road, and off we went! Niiiiice!
On our way home from our Thanksgiving lunch (we celebrate on Sunday, not Monday), we saw an adjacent vehicle trying to keep up with our own. Driving this monstrous SUV, we got a little nervous, but continued to drive along. As they pulled up further, my husband noticed that they're from Nova Scotia.

Husband: "Oh no. I think they think we're from Nova Scotia!!"
Me: "What are you talking about!?"
H: "Our licence plate! I think they think we're from Nova Scotia! Crap! They're rolling down their window! I think they're trying to get our attention!"
M: "What the frigg! We're doing 120 down the highway...I know Nova Scotians are friendly..but common!"
H: "Oh, they're only waving. Common! Wave back!"

I threw on my Nova Scotian charm (I'm not from there, never been there, etc.), I sent them a friendly wave back. That only got them going, and they waved even more frantically. I decided enough was enough at this point and decided to slow down and let them go on their merry way.
So my dear readers, please don't assume when you see a vehicle on the road that that car belongs to the driver. You may, just may, be witnessing a rental car driver--who has had very limited exposure to other provinces, let alone the United States! Remind me to write about my New York licence plate experience!
