Sometimes it is worth teaching English. In spite of the terrible pay and unsociable hours someone, someday will make it sooo much fun.
For example my student who when offered a cup of coffee replied with “Yes, please. But I only drink castrated coffee.” Of course she meant decafinated coffee and I had to explain what castrated meant, but it was fun.
Then the student, who when shown two people kissing each other on each cheek (and they still don’t believe me when I tell them that we do it in the UK sometimes) said to me “Ah yes a French kiss”. Once I had explained to her what a French kiss actually was she took great delight in going around the office asking for a French kiss from her male colleagues.
As I said; sometimes it all seems worth it.
