Been long time away from Britain...makes me forget many simple words. For instance, this morning I could not recall what to say about a thing to stop water from running away from a bath tub. Cap? No. Shut? NO, No.
It is a plug! My Longman dictionary says "He pulled out the plug and let the water drain away" as an exmaple... My god, I should rather say "I pulled out the plug and let my memory drain away from my brain."
Perhaps, I should start writing something in English regularly here again so as to plug in my brain.
