This just came up my mind, I would love to discuss how to deal w
those awkward and difficult situations in real life. How to remind
'cool' or handle it nicely. Ok, giving an example, what if you
suddenly have a stomachache in the middle of a private tution class
or a meeting. Or what if you haven't eaten and your stomach keeps
growling. Please share some situations together and we'll discuss
the best ways to solve it 
Hunger problems- Drink lots of water before meeting if I am
feeling hungry.
Sudden stomach problem- hmm just excuse yourself
