On Thursday, Facebook founder Mark Zuckerberg went back to school. Back to Harvard to be precise - the university he famously dropped out of in 2004 to focus on that social networking platform you may have heard of - Facebook. Mr Zuckerberg gave the commencement address and even received an honorary degree.
Speaking to young graduates, the 33-year-old billionaire had plenty of interesting things to say about purpose and community. But there's one sweet anecdote about his college years that stood out and that's the story of how he met his wife Priscilla Chan. He called it his "best memory from Harvard."
