On a stowaway

I was sorting my gear at the hostel when I noticed there was a bit of my bike computer on a bag of bike tools. Specifically, the magnet that is attached to the wheel. I was alarmed for a few seconds as did this mean Leonardo was losing parts? Then I remembered that I had left the bag of tools on table next to the bits of my new bike computer, which included the magnet. I had left the old magnet on the Leonardo. The new one had been attracted to the metal of the tools and bike parts and thus stowed itself away to Calgary!
