OK, this is about Twitter but I think it probably transfers: I posted this the other week but am still looking for people to agree that these habits between couples on social networks are odd!
Things like:
Always referencing the other person in a tweet so they'll read it, with @snazzy at the end if it's not in the middle somewhere
Using it to have a conversation when in different rooms and make requests, e.g. for the other person to bring them a cup of tea
Always retweeting anything nice said about their partner (e.g. 'Snazzy thanks for fixing our garden fence, it looks loads better now' from MIL, for instance)
Using tweets with partner copied in to indirectly make a point, e.g. 'Wanted to watch Great British Bake Off but @snazzy is glued to Friends instead'
Boasting about stuff partner is doing for them: 'My wonderful partner @snazzy is taking me to @swankyeaterie later, best get myself ready!'
#ff'ing one another persistently
Disclaimers: yes it's none of my business; no, it doesn't really hurt anyone; yes, I probably should get off the computer and get a life instead of being all heated over people's tweets.
But does this irritate anyone else? Or is it only people I know who do it?
