Getting annoyed

Well today was going well but then the 2 new kids cancelled last minute as the parents would not be home in time.....instead of finding out if they would be there later, it got cancelled. I tried to make it clear that I only have 2 more weekends left and it may be too late for them to start..........Then I got a barrage of text messages - what are you planning to teach the kids tomorrow? (ummm photography) - you need to make the lessons more interesting and make them talk to you about other things. Maybe read them a story. (????????????) Why do you just talk about the photos they have taken and photography, why not teach them English? Why aren't you teaching about technique more (well some have only ever taken 2 rolls of film, and actually thats part of dicussing the photos). I really am getting tired of trying to explain my project. Just as I think I have done it well something falls apart like today and I wonder why on earth I am doing this to myself.
