Hi Turnoi
You had me in stitches, the bit about raising kangaroos. But it could be that this visa guy's mind is so full of 'how to do it' that it has submerged his desire to help the Chinese students, so he's not coming across to well yet. He could certainly milk his past experiences for scintillating lesson plans- fork lift trucks, bailing twine, nasty accidents when the pile of heavy boxes topple over and accompanying language complete with expletives. I think you can use your experience to teach English. I have already written a few plans to include beefburgers, food safety regulations, trailers, Handeman running hot water hand washers.http://www.ebay.co.uk/itm/262086889935?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
