It's not just about the theoretical and analytical things that Sir Cacdac shared. It's all about the friendship, values, and laughters we've shared during this whole semester. Those lessons we've discussed are nothing if we don't have that BOND that anyone can't replace. These lessons can be learned from other people. The big difference is that we LEARNED because of the efforts, time, and willingness of Sir Cacdac to make his students outstanding in their future career.
