Communication.  So important, so easily messed up.

One thing I learned over the years is to rephrase what people say to ensure the understanding is equal.  I must admit that I don't always do it, but it's helpful.

I especially have difficulty with people in charge of children's activities who do not communicate well with parents.  I used to work for a woman who drove the parents crazy because she didn't get the point across well.  She would arrange for students to take a field trip but not provide all the little details:  when to drop the kids at the school; what time students would arrive at the hotel.  You know, the stuff parents really need to know.

My friend is dealing with this kind of thing now.  She is dropping her child off at a school but the people to whom she is entrusting her child are not there.  The farm where her daughter is being brought is expecting the daughter; the woman in charge is not there.  It's probably an oversight or misunderstanding, but if it were me, I would be enraged.
