It's funny, this is a very important "protective factor" or "marker" when doing mental health assessments. One of the areas that is looked at is "likability" because it can be quite difficult for those kids that have behaviour issues and also are just unlikable vs. that little cutie that does something "bad" but has a devilish smile and a dimple to boot (and maybe gets a little more leeway then). I definitely have met kids I just don't like and unfortunately like Lou said this can impact our patience with them etc.
