Recently, I was very very surprised to watch ‘’Here comes Darwin!’’ （ダーウィンが来た）,an NHK TV program, where a Japanese scientist Toshitaka Suzuki reportedly discovered that some birds have a language in the true sense of the word for the first time in the world.

Recently my motorbike was stolen.I had parked it in a parking lot and left to do some shopping. When I came back, it was gone. Only then did I remember that I had forgotten to lock it.
