One day, when I wanted to go to canteen with my friend, when I was going to canteen, I sang a song with the loud voice and messy tone, like "aku mah apa atuh cuman selingkuhan kamu, aku mah apa atuh cuman pacar ...". I looked behind, I thought behind me is mi friend, it was not, i was shy because I had sung loudly, it was in front of a boy and finally he laughted and I just smiled with shy face

Maaf kalo salah
