Our Japanese friend living in Daegu, who found out that I had a cold the other day through my homepage, gave us a humidifier that he no longer used at home. When we started living in Daegu, we noticed that the air was very dry. But since we were only going to live in Korea for a year and the electric voltage is different from Japan, we thought there will be no need for us to buy a humidifier. As it started getting colder, the ondol heating was turned on in our dormitory and the room became very hot. With the hot room temperatures and very dry air, it made our throat aches. When we were about to decide on buying a humidifier, our friend wrote me a kind e-mail. Starting tonight, we don't have to worry about our throat aches and have a good night sleep!
