I studied math with Ender during my junior year in the high school.Patience was the keyword at our lectures and Ender showed great instances of enthusiasm and understanding that made everything a lot easier for both of us. His communicative skills were so excellent that he always managed to keep my attention high toward the subject we studied. Besides educational issues, he was also an idol for my sports career as a team mate in the waterpolo team. For me it was great to be able to spend so many hours together in the lectures as well as in the trainings. Thanks for your support and inspiration.
