Formal letter

Dear Mr Flybender,
                                I am Steve Pickless, and I have your time mashine. I am writing this letter because I need to ask you some questions because my mother does not let me use if it is dangerous!! she tells me that I am a kid and I can not use it, but I am fifteen years old.

So, can you tell me please how I can turn on the mashine and how I can use it? and I need your telephone number to ask you more questions . In case you need my phone it is 4214-0251. And the last question is from my mother is the mashine safe?

Well, I am very happy that my mother lets me send you this letter!! and I would be happy if you answered!

Yours sincerely,
Steve
