Farewell to all of my classmate, and to my professor Dr. Rivera. This is not the last time we will see each other again, I'm sure we'll see each other on campus next year. I would like to start out by saying Thank you to all of you for making our class a happy and friendly environment. I would like to wish all of you a Merry Christmas and a Happy New Year. I hope your new year will start out good, and good luck in your studies. To Dr. Rivera, Thank you so much for your encouragement, and helping us excel, I hope I will meet another professor like you. I wish you the best in life. Thank you! Thank you!
