As this Topic is titled with: " a funny thing happened":
not being a native english speaker I had to figure out what DH means for example, I think its dear Husband.
Therefore DD dear daughter, DSIL dear son in law. So I was just wondering what DOG means!? Dear old Granny? Dear other............Grandpa??
After reading that it used to sit on your lap I figured, its just a dog with four legs and no abreviation :oops:
Granny
