Weirdo

Got 2(two) miscalls while I was watching Nanny's Diaries yest(hp on silent mode). From an unknown number. Sent out a text message to find out who was the caller and said sorry tat I didnt pick up the phone. S/he called again as the sms delivered. Me pressed the answer button and say hullo. Apparently the caller is a 'he'.
Excerpting from our really brief conversation :
Me : Hullo?
Him : Are you inside the cinema?
Me : Who is tis?
Him : You inside the cinema, right?
Me : Who is tis? (still in low voice)
Him : Haha.. I am asking are u inside the cinema now?
Me : WHO. IS. THIS? (Start getting irked)
Him : I dun want to say. Just wanna ask u whether u are inside the cinema?
Me : Then OK. (Pressed the "end call" button immed)
Who the hell he is?!?!!!
After some mins, he sent me an sms saying : Hi, why u cut off the phone line?
*Damn!!* He has messed my concentration!
Tis morning, 9.45am. I got his call AGAIN!!!
After several miscalls, I sent out an sms to him : "Please let me know who you are."
He replied : May I know you?
1.30pm : Called again. (not answered)
7.45pm : Sms --- May I know you, Wiwi?
Wat??? Is he someone I know? How come he know my name?
I dun hv time to play wif u! Never use those old fashion tricks to tease me, please! I am insensitive. I never keep an eye on those sneak guys, remember.
