Welcome back ladies and gentlemen of the internet. We all have our boundaries for what we find really offensive. As petty as it can be, we are all human and there will be something petty that bothers us, and that's normal. One person's pet peeve could be another person's everyday life. Maybe someone really doesn't like the sound of clapping, or the idea of shaking hands with someone, mayonnaise, or hearing high pitched voices. We all have our own unique idiosyncrasies that make us different from each other, and when we're in a relationship, these 'petty' idiosyncrasies should be taken with a grain of salt and respected at the very least.
This brings us to the Reddit thread. In this story, the original poster (OP) is a woman who's 6 years younger than her boyfriend. They attend a friend's dinner, in which she contributes a dessert, only to find one of the friends adding cinnamon to the top of the dessert. I would never even dream of tampering with someone else's cooking. But you'll have to read the full story below for all the juicy details.
