I was just reading a post that linked to a chicken breed abbreviation list. But what I have trouble figuring out are the non-chicken abbreviations. I thought I had DH figured out as "dear hubby?" Not even sure on that, but then there are others that totally have me clueless, they start of simple, DD, etc. but then turn into 3 letter DDL, etc. What are all these? And if it is "dear" that's the prefix, why? Why am I referring to my husband's sister in law twice removed as "dear" anything? I'm so confused...
