This text is a good example of the blog as short effective anecdote. It is a mini-short story, with a point.
Take a look at how it is structured, brief paragraphs, (one to each stage in the story), and how it is expressed (informal and colloquial language, sounding like someone telling a take orally).
Write two paragraphs of a similar blog, dealing with an experience that is disagreeable but instructive - or instructive but disagreeable, as you prefer! It can be a real personal experience of their own, or (more easily) an imagined story of themselves in an unpleasant situation.
