Check ups

Everyone needs a check up every year.  Jim and Jean go to their doctor for a check up.  I go to the vet for a check up.  The heater needs a check up too.  Today the heater man came and gave the heater it's yearly checkup.  He threw the ball for me a few times.  I liked the heater man.  The heater is lucky because it doesn't have to have any shots.
