The other day I went to make a purchase for some new flea & tick medication for my dogs.  We I arrived home, I realized that the employee had given me a larger supply of medicine than what I had actually ordered and paid.  By the time I had returned home, the store had closed.  I had to wait until the next morning to correct the matter, but I did go back to make the matter right.  It is important to me to be honest and trustworthy.  Not only this, but my son saw this display; and, thereby, I am teaching him to be both honest and trustworthy too.
So, the other day I had a test of my character.

I had ordered some medicine for my dogs.  When I arrived home, I realized that I had paid for a two part kit, but they had given me a four part kit.

Well, I hope you did the right thing and correct their mistake.

Absolutely.  I had to wait until the next day, but I went back to the store and made the matter right.  It is important to me to be honest and trustworthy.  On top of that, I am trying to teach my children the same.  My son was with me, both when I made the purchase, and when I made the purchase right.  This is very important to me.
