Why Jovie Cries

Today, Jovie spent the afternoon with the Smith's while we were at work.  She was a little weepy during the afternoon.  This evening, I was asking her about her day, and I asked if she had fun at the Smiths.  She said yes, but then she said, "I cried."  I asked her why she cried, and she said "You weren't there.  I was worried."  I said "What were you worried about?"  She answered, "I thought you were lost."
