Whether intentional or not, phrasing something this way could very easily be misunderstood by others as “I spent savings my partner and I had in a joint account on a Pokemon card and never told them.”
I don’t feel @Dyl wrote any of that to make you feel shame (they’re one of the nicest people on E4), but many of your spontaneous decisions are a cause for genuine concern from the perspective of an onlooker.
