Dear Friend,

I’m writing to thank you for your invitation. How could I say no? I’m so glad to know that you will be part of the fantastic musical festival. I guess you must be a little nervous. It is normal, but don’t worry, because I will be there, and remember that you have good friends.

Unfortunately, I won’t be able to arrive get there on Friday, but on Saturday I can be with you all day and share with you we can do all the different activities that you mentioned me in your last e-mail. and I would like to know the cost of tickets to festival. Also, how much do the tickets for the festival cost? 

I know we will have fun that day.

Speak to you soon.

Fer.

<em>Fernando, very good job. There were only a few small things that I had to correct. Just remember to use "because" and "and" in the appropriate places to make compound sentences. Also, I changed "arrive" to "get there" because in this context we would say "I won't be able to get there on Friday." (in American English) The phrase "share with you the different activites" doesn't really make sense. The way we say this is "we can do the different activites (together)". When asking the price of something, we say "How much does it cost" instead of "What is the price of it".</em>
