First, we don't use abbreviations like "hw r u". Save that for texting on your mobile phone. We try to use correct spelling, and correct punctuation - including starting sentences with capital letters, and ending them with full stops.
Second, we don't do all your work for you. If you want help in writing a letter, please have a go at writing it yourself, then submit it to the forum, and someone will be happy to advise you and correct your mistakes - as I have done above.
