Really?!

So, I got another phone call from the school nurse this afternoon - my youngest had a 'tummy ache'.  I couldn't believe it - surely she didn't think I needed to come and get him again?!  I asked to speak to him.  "Are you sure you're sick?"  "Oh yes, it's awful!"  "There are only a couple of hours of school left, can't you make it?"  "I don't think so."  "How 'bout I come pick you up at the end of the day, so you don't have to ride the bus?" "Okay!  I'll be fine!!"  The nurse came back on the line - "It's a miracle!"  "No, he just hates to ride the bus.  I'll see you at 3."
