我刚从宾夕法尼亚大学（University of Pennsylvania）修读了为期4周的古代哲学课程。我知道...我的爱好是不切实际的，但是我在孩子们睡后花了很多小时。感谢柏拉图和前辈们，在过去一个月中收获了很多“乐趣”！

I just graduated from my 4 week Ancient Philosophy course with the University of Pennsylvania (@Penn). I know... my hobbies are very impractical, but it took a lot of hours after the kids were asleep. Thank you Plato and predecessors for all the "fun" over the past month!
