I had to sit opposite a bloke at work who ate with his mouth wide open. I cracked one day and told him to shut his mouth! He stopped speaking to me but he did shut his mouth. I was then moved (he was a serial complainer to the boss) and sat opposite a bloke who literally had his finger up his nose all day. I could actually cope with that better.Those things are like death by a thousand cuts.
My Ex and I used to joke about the little things that irritate you about each other, which over a long relationship just get more and more annoying...you either have to learn to ignore them or get to 80 and end up beating your spouse to death with a rolling pin (or other kitchen utensil of choice) at the breakfast table because you just CANNOT listen to them chew loudly/ stir their tea repeatedly/ scrape the spoon in their cereal bowl one more time![]()
This was in a professional environment.
