If your child keeps making the same mistake in, say, writing stuff, do you get impatient/exasperated/angry? And if you do, do you communicate any of those emotions to your child?

Is it wrong to show them those emotions when you know they can do it if they try hard enough? If it is wrong, do you just keep pointing out the mistake over and over, or ignore it and hope for it to disappear by itself?
