I used to take some days off when I was a pupil. When I had cold, I would say to my mother, "mom, I have fever", and lie in bed the whole day.
I would listen to the radio, and read my favorite books. I would ask my mother to bring my favorite foods, such as a pudding, and eat them straight away beside the bed.
You guessed it right. I rather enjoyed the experience of being sick in bed.
Nowadays, I seldom spend the day in bed even if I feel not so well. Yesterday, according to my own standards in childhood, I would have been classified as sick. I sneezed, and felt feverish. Despite the deterioration, I stalked the streets of Tokyo all right, and worked diligently once at desk.
When I look back on the carefree pupil days when I could take the day off just like that, my heart is filled with a strange and sweet nostalgia.
