Our job candidate, who is a native speaker of Portuguese and a teacher of Spanish, greeted me today with a recital of a poem by Pushkin. In Russian. Then he greeted my colleague who teaches Chinese with a long phrase in Chinese. Then he spoke in Yoruba to a colleague from Nigeria. Then I felt so bad about the puny number of languages I speak that I retired to my office and almost avoided hearing him talk to other colleagues in German and French.
