So, have you noticed that people, like animals, behave less than optimally when under duress? It's counter-intuitive: when most in need, people, like animals, tend to repel their possible sources of help, comfort or solace. When most in pain, exhausted, scared, upset, demoralized, at sea, or distraught, people, like animals, are most angry, defensive, vicious, sullen, dictatorial, combative, or withdrawn.
I am living with a small, angry, new cat who glares at me, hits the other animals and will only eat pancakes (scared, at sea).
And a toddler too excited by life to sleep (exhausted).
And a Husband who recently had dental surgery and still has a raging infection (in pain, exhausted).
