Families can literally fight over anything, even something as mundane as a name. But wars have been fought for far more ridiculous things, so this doesn’t really come as a surprise. While family conflicts are pretty common, the way they are handled and resolved differs on a great scale.
But there are some people who just tend to worsen things rather than fix them. For instance, our original poster’s (OP) brother and sister-in-law will definitely get the crown for taking things too far when she named her son ‘Oliver’, which was similar to their daughter’s name, ‘Olivia’.
