Occasionally I am asked if I ever have any trouble with individual tour members during a tour. The same might be asked about students in a class. After 45 years of directing tours I would have to say that there have been a few people who have given some problems for me or other tour participants. If they give trouble to others, that becomes a problem for me.
Mark, one of my friends, showed up on the first full day of touring with a T-shirt that I suppose he thought might help.
Really, the serious problems have been few and far between. I have become friends with some wonderful people through the years.
The advice of wisdom always works.
A soft answer turns away wrath, but a harsh word stirs up anger. (Proverbs 15:1 ESV)
