Imagine I am a Cow! ( THE ARTICLE OF COW! )

Imagine I am a Cow! Muttakin Rashid Alvi No, I am not joking at all! I am serious about this! I am really a cow now! So let me SHOUT, “Humba!’’ At least for some kind of harmony for sometime.                 My eyes see and feel many bad things happening around the planet. But the only thing that I can do is SHOUT, “Humba!’’ Because I am a teen aged cow and my horns aren’t too long let alone being sharp.

TRAPPED IN A CLOCK’S TRAP! Muttakin Rashid Alvi     What a ridiculous situation it was at a Malaysian Hotel! I was sleeping in our room. There were two beds in the room — for me and my sister. While I was having a mellow dream, an alarm (set in my mobile phone) went off loudly. It ruined my sleep. To my horror, I saw on my phone that it was 4:30 am and my sister wasn’t in the room. I searched for her everywhere in the room. Then I ran out of the room. My parents were in the next room. I knocked on their door vehemently. Not a sound came out from the room. I returned to my room and called the reception. I told them that my sister has disappeared. They kept saying, “Disappear? Disappear? How? How?” I was crying and wondering why would my sister go out without informing me at the wee hours. This was our first time there and we didn’t know the place well yet. That thought made me more anxious. Moreover, my sister’s mobile phone was in the room and after calling my parents I found
