lol

Grown ups don't understand some things like lol and brb and my mum sais nm is a waste. 'its just silly" she sais "people say 'hi, hi, wuu2, nm u?, nm' and thats it' my friend asked me what wuu2 means saying the letters out, i say wat u up too and she sais, wow i didnt think u knew that.
And that proves i do know wat wuu2 means and adults dont understand!
