I was visiting my friend one day, and I was taking the bus back home. When I was walking to the bus stop, my sandal strap gave way, plus the entire bottom part of the shoe was hanging on by a few strands!
I had an umbrella with me, so I took the black cord off the handle (using a pen to do that) and then I tied it in such a way that the bottom of the shoe was strapped securely to the rest of the shoe. I then used a safety pin to attach the strap back to the shoe.
That was able to get me back home safely, but with sore feet, but oh well.
I felt like quite the MacGyver :)
