DH DD DS abbreviation annoyance

What's with people using these abbreviations??? Yes, i understand they mean "dear husband " "dear daughter" "dear son" i know this because more times than not the people who use these abbreviations type it out in parentheses to explain what it is example: "my DH (dear husband) and i were shopping the other day and....yada yada yada" doesn't that kind of negate the use of the abbreviation? Sorry it's just really annoying to me and I don't see the point whatsoever.
