Some of the tougher problems I've had would be when I was doing substitute working with small children. You know, oftentimes I get in there, they won't have like anything laid out for me. You know, that's what they're supposed to do for you is leave out stuff so you can look at it and go forward from that day. So I'd have to improvise. I'd have to think of new ways to help them learn and generate an idea of how I could keep their attention once I was there. That often became difficult, especially when you're dealing with small children and I could even work even the same way with adults half the time. I've learned that when dealing with it, I had to basically find the thing that they were interested in and go from basic from there. Like the lesson for that day, whatever it is about math, science, you know, whatever we were doing, if they liked that subject, I'd go on from that and do something that they would help learn from. And that's how I've dealt with situations. I try to think off the top of my head and go from there when it gets tough. Thank you.
