Talk about fire engines

My son asks this questions every day.  "Talk about fire engines".  I ask what do you want to know?  He says, "Just talk about them."  I have gone over the ladders and the sirens, the purpose of a dalmatian and the pumps and I am running out of things to say.  Now I have introduced a new fire engine character: Sparky.  Sparky has many adventures which usually relate to what I want Matt to do.  Here is a story that I told when Matt would not go to bed early but would complain that he did not have time to sit in our bed in the morning before school.

One time after a long day of fighting fires, Sparky came back to the fire station with the other engines and wanted to stay up late while the other engines went to bed.  The next morning the fire alarm rang and all the other engines got up and went to the fire.  Sparky was too tired to wake up.  When Sparky finally woke up, the other engines were returning to the fire, Sparky was upset that he could not go to the fire.  That night Sparky went to bed early and was able to go the fire the next day.
