Afterthat, we switched our TV on and saw what happend in Japan, so our work had almost stopped afterthat.

Goldsmith College, UK

Image
When I was a graduated student, I went to London and enjoyed summer school at Goldsmith college for about a month, because I wanted to spend good time at that period. Goldsmith college was located near New Cross station and I stayed at dormitory of this college, because at summer time, dormitory was empty due to the summer vacation time. And I happened to watch Flickr yesterday and search the word "New Cross", then found Goldsmith College's & around this area's picture and felt longing for this town. New Cross is located about half an hour from central London by train, so it is very convenient place to go around central London. And this town is not so big (in another saying, feel a little deserted-looking), so I enjoyed the fist experience of abroad in a relaxing mode, so I liked this town very much. If you see this picture , you can see the dormitory(*) where I stayed about 20 years ago, so I am deeply moved. (*) UK's college is started at September, s

Our new family !

Image
He is our new family and he is our first baby! He was born on 28 May, and this Wednesday he came our home from hospital and 4 days had passed. He is very very bouncing baby so my wife couldn't sleep well, but we love him very much. He cried very loudly so we tried to ease him in various ways, and this picture is one of ways to be quiet. (this red material is a rattle and if I shake this rattle, he is very curious about it and hear this rattle's sound and sometimes stop crying!)
