Me giving tution?

Yesterday, Eng Choon had called me on about whether I was willing to spare my time in giving tuition to the 6 secondary 3 students in kovan. I would be teaching chemistry. I accepted this offer because I thought that one day, I also would have to work. I have to get some experience from working and this is one way that I can do it. Initially, I felt nervous at the thought of giving a lecture to 6 students. Suddenly, there are so many "what ifs" in my mind. What if I cannot teach them well? What if I cannot crap lame jokes? What if they are bored at my lecture? However, for now, I have started to calm down and plan for my 2 hrs lecture.
In the first 15 mins, I will be like introducing myself and ask them their names and their interests to chemistry. In the next 30 minutes, I will be teaching or rather revising with them on the topic on the particles nature of matter. I will be asking them about the things that they have known. After that, there will be a short break of about 5 minutes.
Later, I will be like giving them homework to do for the next 45 minutes. I hope that the plan goe well and the tuition goes on smoothly.
Regarding to my mom's sickness, she has improved quite a fair bit although for now, she still has cough. Now, three family members in my family has cough. Sigh!!!!
