At what point should one give up?I've tried helping them out by having them shadow me.  We agree to break a minute, and then they go missing in action for a while...then just go back to their desk.  Even when I know they've done this, part of me feels like I shouldn't have to go get them but that they should be showing interest in learning.  Frankly, it's a bunch of time I don't have explaining things as I go when I could just do it.  Am I expecting too much to expect that if they want to learn they'll make sure I know they're ready and willing?They go to meetings that they were not told they had to attend...good, but then sit in the corner and sleep...bad.  I don't even know what to do with that.Sometimes I give them something small to do and they do it great, so I give them something just a touch harder and they totally fail, hard.They check in things without testing them.Part of me thinks that maybe I should be spending more time with them but at the same time I don't see a lot of interest and I really, honestly don't have time teaching the same things over and over.  Sometimes I get asked questions that are really, really easy to answer if you just do a little bit of your own work trying to find out.  Other times I'm not asked anything.I'm sure I could be doing better but honestly...I don't really want to anymore.
