Whenever someone is having "a moment", start at the top of this list and work your way down:
- coming down with something?
- needs a break?
When you find the problem, administer the appropriate remedy with ample amounts of empathy and affection. If all you have is empathy and affection, apply liberally while you seek the required treatment. If you are running low on empathy and affection, apply anyway--they are self-renewing resources.
