My house has no dong

This morning just after nine, the first of today's home repair personnel arrived.  He is out in the front yard digging a trench from the city's sewer line to my house.  He's being very careful, and I appreciate it.

He got a few feet of trench dug up, and that's when the water damage guy arrived.  He left, but came back and rang the bell again.  The total number of times my doorbell rang today so far has been three, and every time, it reminds me that my doorbell dings, but doesn't dong.  It goes ding-click.  

My house has no dong.  Tee-hee.
