I found MAGIC!

It was a rainy monday night and i was hangin out with some colleagues enjoying hot chocolate and coffee while suddenly the coffeeship played a reggae music that was quite fresh for my ears.

Misteri Anjing Dalam Keranjang

Jumat malam kurang lebih sekitar pukul 21:00 gw berencana pulang dari kantor ke rumah. Handphone berdering, terlihat di layar handphone, nyokap yang memanggil. Gw kira cuma pertanyaan biasa, "Pulang malem?" atau "Nunggu macet ya? kok belum pulang?". Tapi kali ini pertanyaan itu gak ada sama sekali.
