Confusion

I was walking on the alleyway of COMA building. It was noisy with many chattering of sitting happy student. I peek to lecturer's office and saw Mr. Slug is sitting in his table reading something. I continued walking to my designated classroom at 209 in the second floor. I saw Doris and two other student chatting about new guidance on Song III class. "Hai." I said. "Joe kamu udah dapet materi baru dari Pak Slug?" asked Doris.

"Belum, aku belum dihubungi kok." I answered.

“Oh, terus kita nanti belajar apa?" asked her.

"Mungkin materinya masih dibawa pak Slug." I said. After a moment or two, more students or my classmates come and ask me the same thing or the other to make conversation. I decided to take out the assignment that Mr. Slug had me to do. I said, "Aku akan mendatanginya untuk mengumpulkan tugas ini sekalian bertanya tentang materinya."

"Okay" some answered. I walk to lecturer's office and meet him." Permisi, pak." I said politely. "Ya?" was the reply.

"Saya mau mengumpulkan tugas song." I said.

"Ya, Sekalian ini di bawa mas, yang atas sendiri, materi untuk minggu depan dan yang lain materi untuk nanti." He
said.

"Baik, pak." And I went upstair. I enter the class and say, "Hey ada materi baru tapi cuman segini." I took one and left, thinking how cold is the world.
