Just remember that although Michael is strange and looks weird - it doesn't mean he is an abuser. Lacking in judgement - yes; but he is still innocent until proven guilty.
Also - please remember that abuse comes in all forms. We quickly recognize abuse when we see a child with bruises from a fist and we recognize the trauma from sexual abuse too. The "sneaky" abuse though is the verbal and emotional abuse - it can take so many different forms - from calling the child "stupid" to saying simple things like "Why can't you be more like **** they're so perfect!".
