I know right??? Once I almost texted my friend "Lets meet in the dumpster, scarecrow" and what I meant was "Lets meet at Danny's home, stalker"!!!
Urmm... It's about finding a balance, between formal and informal grammar. I, personally, like to talk formerly around people I don't know. If I was talking to friends, my typing suddenly goes mellow, u know what I'm sayin? Just my two cents
And people living in a english speaking country are lucky! I live in a French speaking country and here the "cool" ones talk a dialect called verlan... Which consistes in changing the normal way of the word... Cool becomes looc... Now try and read a text message when cool all of a sudden becomes LoC
