Mobil Bau Keringat
Being single means: "God gave you time to chase your dream on your own". Lebih kurang itulah yang terjadi pada diri saya saat ini. Tidak punya teman berbagi, teman bercanda, berantem, bersentuhan (lho?). Pokoknya semua dilakukan sendiri, semau gue, ga peduli, lempeng aja, bebas merdeka dan mengenaskan.
