People also ask
- Does lmk mean they like me?
- Not directly. While it shows they're engaging with you, "lmk" itself is neutral. It means they want information from you, which could be about anything.
- Is lmk rude or passive-aggressive?
- Usually no. It's a very common and neutral abbreviation. It's only rude if the context or the sender's overall tone suggests it.
- When should I reply after they say lmk?
- Reply when you have the information they're asking for or at least when you have an update. Don't leave them hanging forever, but no need to rush if you don't have an answer yet.
