I sometimes say 13 hours, sometimes 14 hours, depending on how you count. 7:40–21:50 is 14 hours and 10 minutes, but at noon there is 1 hour and 30 minutes, at night there are 40 minutes, and if you subtract it, then it is 12 hours. If you subtract the recess, then you also subtract 85 minutes, then that’s 10 hours and 35 minutes. If you say to an adult that school is 14 hours, you will definitely be criticized for overcounting your study time, lacking motivation, and not meeting their expectations of you being motivated. Sometimes, definition is an important thing because it involves how people’s brains deal with the shame that someone else scolds to them. Some of you may be Americans. One example that comes to mind is that the definitions of the words “freedom”, “democracy”, and “republic” must be sensitive to some of you. If you’re a person who is in a culture of shame, the definition of each word is sensitive, as each word will be used to scold you, or be used to promote the reasons for the rules that bind you. The culture of shame is global; you can feel that.
