weird text message

Just the other day, I received a text message coming from an unknown person. He asked if I wanted to be his text mate. Since I was bored to death, I agreed to be his textbud. This was how the conversation went..

Grey: Hi Dianna!(grrr..I hate it when people give me the wrong spelling) do you want to be my textm8?
Me: cnu 2?
Grey: i'm Grey frm MaSci. I hope that you don't mind me toking 2 u?
Me: oki. wla nmn gngawa e. hw did u gt my n0. b?
Grey: i gt ur n0. from my friend's friend's friend. I was asking my frend in admu if he knew any reasonable gurl in admu nd it led 2 u

By this time, i was freaked out. Am I supposed to be flattered? the hell?! i have to call gi to calm myself. do guys really do that?
"Pare, I need a reasonable girl. Do you know one?"
"Wait lang pare, I think may friend akong may kakilala na ganun..O eto this is her number..she's..."
Is this normal???

Me: frm wat schl r u?
Grey: i stdy at UP BAA
Me: i mean, frm wat HS?
Grey: Manila Science..u?
Me: grace christian
Grey: i heard dat ur frm the star sec. i'm sure dt ur gud in math (I'm now thinking who from my acquaintances gave him my number. Imposible kung from invictus. They know I'm not good in math=p)
Me: no,mediocre lng. bt i try to be gud at it.
Grey: i dnt think so. um, im going to fetch my mom at rockwell. it ws nice toking 2 u.
Me: ah oki, bye

And that's how the conversation ended. I don't know. Feel ko niloloko lang ako. Anyways, text lang naman dba? no harm will come to me. He's at UP naman e. And it's been two days since he texted me. So no worries..haha=p
