“Don’t ever take a fence down until you know the reason why it was put up.”
Stress might be getting the better of a household member today. This person feels emotionally volatile. The least irritation could set off a temper tantrum. Try to ease the pressure by staying out of the way. Don’t offer advice, however well intentioned it may be. This person needs to come to terms with whatever is bothering him or her. Distance yourself and do your own thing.
