I recently came back from a winter break and have started working again... only to immediately run into the dilemma of people sending me cliffhanger messages again.
A year or two ago, I discovered no hello and have thought about it often since then. I've even sent it to a few people since then (who wouldn't take offense to it).
I work in a fast-paced environment where efficiency is extremely valuable. Therefore, I have always held a deep displeasure for conversations where people start with "Hello" and then.
I searched back through my work messages and found that I received ~50 messages from ~10 people last year from people that contained "hi", "hey", or "hello" and did not contain any indication of the purpose of the conversation. I also noticed that a few of the users were responsible for the large majority of the cliffhangers.
There's no real point to this post, just a desparate request for people to please stop doing this.
