So, the other day I had a test of my character.
What happened/
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.
