When composing an I, Anonymous, why does everybody direct the letter to the person they are complaining about? Chances are that person/those people will never know about your rantings. I mean, I get it, but why not speak directly to your actual readers? For example, you could say, "So how about this homeless person, sales clerk, bus driver, boyfriend, girlfriend, sister-in-law, random asshole on the street, driver, cyclist, bartender, client, co-worker, customer, pedestrian who really pissed me off?! Here is what s/he did..." That, or simply tell the story in a narrative form using first person, or third of you're that kind. The Dear (insert perpetrator here) template is growing old. Think outside the dear.
