I want

At a farbrengen someone related that when he was a bochur his parents sent him to the Brunoy Yeshiva in France. The physical conditions there weren’t the best so after 3 months, the bochur wanted out. He was a bit of a rebel and decided to approach Rabbi Nissen Nemanov to tell him that he was tired of the place and wanted to leave. R. Nissen then responded “Vos is the Ich, und vos is the vill?” What is the “I” and what is this “want” !
