Not similar with these scenarios. This is one of my hobby and love to share what I have so I do not face numerous challenges like these scenarios. The similar things is I worried that I am not qualified enough to share my knowledge but I try to update myself every time and everyday. After learning these scenarios, I also get a lot of knowledge and I realize that being  teachers in border area, conflict area, or refugee camp is not easy as people think. I've never faced this kind of situation but I feel proud of them that they can handle it very well. I really appreciate of them.
