A read this advice a while ago, and now it hurts me every time someone goes "Hi (name)" and then you just sit there looking at the 3 dots indicating they're writing something.
Or worse,
"Hi (name)"
"How are you, all good?"
"A question"
"Do you know anything about (system)?"
"I have this problem..."
Just have a bitnof respect for my time and attention and write your damn message already.
