Doodledog One of my daughter’s chums, who I think the world of, has been doing the “like” thing since they were at school. She’s now 47 😁 She has a degree and a fairly high powered job. I’ve watched other people have a conversation with her and it doesn’t appear to bother them at all. It makes my teeth grind.
And I would definitely make you scream, I’m partial to a “Not” and admit to using “uni”. However, if I was writing a formal letter, I wouldn’t use either, so it very much depends on circumstance.
