In my Canadian wallet are:

~ $6.00
~ Library card from my old town
~ High school library card from my old town
~ An expired Blockbuster gift card
~ A Canadian key card from a Canadian hotel from my freshman high school trip to Canada trip, last year.
~ Another Canadian key card from a Canadian Quality Hotel from my freshman high school trip to Canada trip, last year.
~ A membership card to local pools from my old town
~ I used to carry around a note from my ex that had 10 things she "loved" about me. I carried it around for about a month even after breaking up, but I shreded it up a couple weeks ago.
