Every time I encounter it, in whatever form, it’s a gigantic headache that makes everyone’s life worse off and as far as I…
Before we go any further, one thing that I want to make clear is that the word assume is going to be doing some heavy lifting throughout this post. This was a rabbit hole that I recently went down …
