The 'Today You, Tomorrow Me' meme originates from one of the most famous comments in Reddit history, posted by user rhubarbs in 2010. The story describes a man who, after being ignored by many others while stranded with a flat tire, is finally helped by a family of Mexican immigrants who refuse any money for their kindness. When he asks why they did it, the father simply says, 'Today you, tomorrow me.' This phrase has since become a global symbol for the 'pay it forward' mentality and universal empathy. In internet culture, it is used to celebrate random acts of kindness, highlight the importance of community support, and serve as a reminder that everyone faces struggles and deserves compassion.
