Grammar - Writing. Informal email page 15

Hi Sofi,
               How RU? It's been so long we don't chat.
I'm writing this letter 2 tell U that next Friday night my parents R going 2 throw a me a party because I got good results at school. It will be GR8. All my school M8S R coming. IMO we will enjoy it a lot. My parents ask me for help to organise this big party, so on Tuesday would you like to come to sleep to my house and help me 2 plan it.

                        Please answer me so I know how much food my parents have to buy.
BTW I invite your sister too.
I hope your parents let U and your sister come and we will dance all night long.
                                           
                                                     LOL
