When the kids were little, I would quote this line. As I pulled into the driveway after a long trip, I would say "home again, home again, jiggity jig." Eventually, I would just say "home again, home again" and they would finish "jiggity jig".
A few months ago, I did this again, "home again, home again" and my daughter finished "jiggity jig" without even thinking about it.
Internally, I smiled. I hope they continue this little ditty with their kids.
It's good to be home again.
