Funny story... when I got my birth certificate when I was eighteen, my name on it was wrong... or rather, my parents had been calling me, and everyone had been calling me something different for my whole life... it was something of a shock. Both parents blame the other one, and I still don't really know how that happened.
Anyway... when I went to go get my driver's license, even though all of my IDs except my birth certificate said the one name, they wouldn't give it to me with the name I've always gone by, so I had to pay to legally get it changed. I almost got thrown out of the registry too, because I refused to swear on the bible, and offered to swear on peter pan... and when I was asked for a non-family member to vouch for who I was, I said that that didn't make any sense, because if they have no way to know that they must know who I am, like they do with a family member, that I could just go pay some homeless person to claim to have known me for five years. Quickly following that up with "not that I'm going to do that"...
When it finally was said and done, they left out my middle name, and I had to get them to do it again! Then they misspelled my middle name on my driver's license, which was itself something of an obstacle, and delay when I got my driver's license changed to a difference province...
Not looking forward to that again...
