I went DC for a conference for four nights. Joe comes from Shanghai and is very nice guy. I am glad that we can talk in Chinese. He made me to feel comfortable as at home. Definitely, he is a good host and met him for one night. However, he has a roommate who is not chinese, and hosted me that night I arrived. At that time, I realized that I was in touch with him instead of Joe. It seemed that there was an issue of using the shower in the morning for two of four morning. He got up at 8am right before me and used the shower for over half an hour until I knocked at the door twice. I cannot imagine that it takes a man that long to take a shower. You need to make an arrange to use the bathroom, either before him or after, then you won't have an issue like me. In addition, the bedding and towel is not fresh, smells weirded.
