Why is there always something sharp in my shoes?

Every bloody time I wear shoes, there is something sharp inside them. I always check before I put them on; I shake them out to avoid this unfortunate circumstance, but to no avail. If there are no sharp things in them to start, they get rocks in them. Without fail, my feet get poked. I hate it.

And don't even get me started on the spider webs.

I walk down the laneway three times a day, and every single time I walk through a spider web. How do they remake them so quickly? Why are they so intent on getting their webs accross this specific lane?
