Interacting with friends, coworkers, mates, and children will reveal the inner workings of a person. Being irritable can cause bodily aches and pains, tiredness and nervousness. The mind can become weighed down by burdens. Granted, the irritants may be small, vague ones. All a person may say is, “I’m anxious, afraid.” Maybe he can’t tell you any particular thing that is bothering him. But he knows something is, and once in a while one particular sore will fester till it breaks open.
