People's thoughts, wishes, hopes and desires... We live in a time where technology can read everything in your mind, and yet, this place teems with people who hate, lie, steal and try to harm others. If that's not irrational, then what is it?
A beautiful flower too will eventually wither and fall. That's the fate of all living beings. If that's the case, it's only natural for one to want to stop the time while they're still blossoming in all full glory.
