It isn't easy letting loved ones make their own mistakes. It goes against your good sense, better judgment, and protective instincts. Who wants to see someone you care about fail or get hurt? Nevertheless, experience is the best teacher, and there's no way that this person will learn without suffering a setback. Remember that scraped knees get better, bruised egos heal, and broken hearts recover and grow stronger. Be a hovering yet benevolent presence, and your loved one will thank you one day for having the presence of mind to step out of the way and the generosity of spirit to allow rather than forbid.
