Hello. So the biggest challenge that I've had in my current job was actually this one child and older toddlers between one and a half to two years old, two and a half year old. And the head teacher at the time was getting ready to go out on maternity leave and he was a very challenging child. We call him challenging. And when she was out on maternity leave, I actually was in charge of running the room, even though I was only assistant teacher. Didn't matter. I knew the room, understood it, read the kids very easily and they knew me and trusted me. How I did, or what I did to resolve the conflict or issue or problem, I actually, very simple. I just spoke to the parents because we were all running out of ideas on what to do. I just spoke to the parents, gave them ideas. I worked with them. I did care calls. I just kept them up to date on things of what I did in the classroom with their child, just so they knew going forward what to do. And they actually wrote the, and this parent from what I understood was a very difficult and tough parent. And she left a very nice email and I have it to this day. It's one of my very famous accolades. And if you ever want to see it, just let me know. I don't mind sharing that with you, but yes, that was one of my biggest challenges I faced. And I was very proud of the outcome because they loved me for it. They respected me very much.
