I'm on my way home.
I had no idea how cold it would be getting in this morning, but as it was neither so cold nor rainy at that time, I put on a short denim and shirts.
I think it was a huge mistake, because now it's quite cold and raining!
Weather forecast said it would be sunny around the noon, though.
I learned I should bring a jacket or something to keep warm even if the forecasts said it would be warm.
So I hope I could get home as soon as possible and would not catch any cold.
