I find it difficult to tell the difference between a lazy user and a user who would rather spend their time on different priorities.
I do as well. Honestly its more important for me to know when I'm being lazy vs prioritizing. Doesn't really matter if I can tell in others. I can't and don't want to control them. If I have an agreement with them and they aren't getting it done... well I don't really care if it is laziness. It just needs to get done.
