On a humourous note, two weeks ago as I was waiting to be processed at customs and immigration, I was certain that I was going to get a secondary. When I was away, my tooth had decided to flare up and when I saw an endodontist there, I was notified that I'd have to receive a root canal when I got back to Canada. My jaw was barely functional. It was extremely painful just to close my mouth. I looked like I was squirreling away nuts for a really long winter and to top it off, I had a mouth guard that I was using so that I could actually talk without doubling over in pain. Unfortunately, this made me look like I was a 16 year old kid with braces in her mouth. Between my barely audible mumbling, the meds I was on, the mouth guard (and I'm quite certain some inadvertent drooling), and the agent's question of "you went there all by yourself?", I was pleasantly surprised to find that the agent had not recommended a secondary.
