The letter*

Dear Manoon!  
Thank you for your letter! I didn’t expect to get it. I was agreeably surprised. You know that this year I'm entering the university. So, I had an intention to pass my last test and fly to you. But my plans were broken: the schedule of the independent testing has been changed. Unfortunately, I have to apologize for being unable to come. I hope that you understand me.  
Though,  I have a good idea, I am able to come to you later in the summer if it is possible. So, I'm thinking about that.  
I am looking forward to hearing from you as soon as possible.*  
The best,  
Lolo!
