I seem to have caught a cold from my son who had been coughing and snorting for the whole last week. He might been have over-excited about his new environment. No fever, fortunately, so he had gone to the school everyday. And then, on Sunday, he said that, he felt so tired that he didn't want to go out with us and stayed at home alone for the first time. So the rest of us three went out for an hour.
