I remember the day my mother taught me how to tie my shoes. She first showed me how to do a standard (around the tree) knot. Then she showed me the two loop (bunny ears) shoelace knot. I found the two loop one easier to understand, so I tried it and tried it again until I got it (I think most people do it the standard way). It's amazing, though, how you do it every day without even thinking.
Speaking of shoes, I can remember owning a pair of these in grade school:
See that cool zipper on the side? You could put a few coins in there if you didn't want change in your pockets. I felt like I could run faster with these shoes on, too, since they were named KangaROOS (we all know how fast kangaroos can hop).
