Very light hearted post here and I am 7 weeks pregnant so likely just being a hormonal grump, but all the abbreviations to refer to family members drive me mad! It takes me longer to work out what means what than it would for the person to just type "mum", "son" etc. Many of them are only one letter longer than writing DM/ DS and it doesn't require a caps lock press!! I know that it's not that hard to figure out really, but they always look so similar that I do have to pause and think about it and it affects the flow of anything I'm reading.
It's even worse when trying to figure out long stories about step families, and also figuring out the differences between DSs (sisters) and DSs (sons).
Why do we insist on abbreviations for EVERYTHING here?
