"火曜日以来、世界は悲しかった。"

Simplified Meaning:

Imagine a day when something terrible happens, like a big news story that makes everyone feel upset or worried. It's like when everyone was sad after hearing about a natural disaster or a tragic event. The sadness doesn't go away quickly; it lingers in the air for days, affecting people's mood and behavior. This quote suggests that something happened on a particular Tuesday that left people feeling down for an extended period. Every time something notable and sorrowful happens, it leaves a mark on people's hearts and minds, making it hard to return to their usual happy selves. To relate this to everyday life, think about when you hear bad news about someone you care about or something stressful like a difficult event at work or school. It can make the rest of the week feel gloomy and heavy. So, it's important to acknowledge these feelings and find ways to cope, like talking to friends, engaging in hobbies, or taking extra care of oneself. This way, gradually, sadness can be lifted, and people can find their way back to happiness.
