Looking from the back of the camera, on the right side theres a small, indented hole with a place to thread the small, thinest end of the wrist strap through. It can be tight to get it through there just by pushing on it...try wetting the end of the strap like needle/thread type thing or find something real small like a paperclip, blunt end of a needle etc to push it through. Once the skinny end is through insert the thicker end through the loop and your done.
You can go on the Canon website, support section and download the manuals, instructions etc for your nice camera. Type the model number is the search box at the top of the page.
Young, old doesnt matter some of this stuff drives me nuts too !!
