Sly guys
Some of these guys at the border think they're pretty smart detectives and that they are going to catch you in some sort of trip up by asking you questions to things that look suspicious on the surface.

Today went like this:

Him: Where is home for you?
Me: Longueuil, Quebec.
Him: Where are you going?
Me: Birch Bay. I am packing the house up over the next month to move everything.
Him: What do you do for work?
Me: I am a stay at home father.
Him: Who works?
Me: My wife works.
Him (slowing gaining momentum): Then who is taking care of your kids if your wife works and you're out here?
Me: My two teenaged kids are taking care of the younger kids.

Then he proceeds to look at me for about 2 seconds, looks at my passport (to determine my DOB), does the math in his head, looks at my face a little more closely and says "you can go."

Yes, I have teenage children. Thank you.
