Mind you, I've been amused or revolted or anything inbetween by the bloopers. Ranging from the wrong roses in medieval Europe -- which were single or double, and by the way, yellow roses are overwhelmingly derived from the roses Napoleon brought back from Egypt (Josephine having a serious interest in roses) -- to having the medieval parents and midwife hang about waiting for the priest to arrive and baptize the baby instead of using the water they had hanging about for just that purpose.
In a fantasy, of course, you can ignore that. Sometimes. More or less. Depending on how you build the world. When the author held forth on how a high-born lady would put a lot of her life at risk by wandering around unattended -- well, I've got a princess, no less, setting out to seek her fortune. I've also got The Three Heads of the Well to cite in my defense. Ha!
The young princess, having lost her father’s love, grew weary of the court, and one day, meeting with her father in the garden, she begged him, with tears in her eyes, to let her go and seek her fortune; to which the king consented, and ordered her stepmother to give her what she pleased.
I cite that one rather than the "All Kinds of Fur" variant because the reason is the slightest. Convenient for giving her freedom to go as she wishes, though, of course, having other problems. There are still bandits. And other problems.
Though that, of course, is that world. There's another story where I had to make the heroine rather more desperate to set out alone. Not living in a fairy tale world, she faced a lot more danger in doing it, even in the social realm.
