Katie loves to greet the guards at the gates when we come on post. When we stop for them to check my ID, she always rolls down her window and says "Hi!"
Yesterday, the guard smiled back at her and said, "Hi! How are you?"
She replied, "I'm doing good."
Once we drove off I said to her, "You know honey, you should say 'I'm doing well', not 'I'm doing good'. When you say 'I'm doing good', it means you are working with the homeless, or helping orphans, or volunteering for charity. 'I'm doing well' means you aren't sick."
Katie replied, "I didn't understand a thing you just said."
