Random mood swings

Is it me or does it seem like your significant other picks and chooses what thing is “too much” and they get a full blown attitude ? I honestly don’t even know why my boyfriends mad right now lol we were leaving his house and all of a sudden it clicked in his head that he should be pissed off and he all of a sudden cared that I didn’t finish some Frosted Flakes lol. We just pulled up to my house and he was still pissy and didn’t wanna kiss me . At this point in our relationship I try to ignore his random hissy fits when they happen because I’ll end up getting myself all worked up. Is this just me?

What’s the dumbest thing you’re significant other has gotten mad at you about ?
