These seem very hard to handle indeed, and probably nothing like the little arguments written on that page, at least at the top (I haven't read everything). There are definitely people who like the little arguments. If you trust each others, you know it's not important. It must spice things up. It's part of the fun. It builds complicity. It's probably a bit like teasing. At least, that's how I feel when reading that page. The little arguments become serious when they are about stuff that cause frustration to the level that the frustration grows (slowly) over time and becomes unbearable. Those things are to discuss seriously. You can't have such funny little arguments on things that make you uneasy.
I'm not currently experiencing much of such little arguments, not sure we work like this, but I like a little teasing for sure.
Good luck and take care.
