I am really thankful to each and every lesson of yours, Ricky. You spot a smattering about my English, and correct them easily. Thanks to you, I'm coming to express my thoughts bit by bit. But it sometimes ends up in showing a half-baked knowledge though. Having said that, once you change it into a correct phrase and then my understandings will be 'fully-baked' eventually. Ricky, I like your lesson. P. S. Thanks for teaching me in such a noisy ambiance on my side.
