Ithink that is all what I wanted to tell you,when I will see you I will tell you a lot of other interesting things about my life. with Love easty Letter. Hi, Jane! It is me Karlis, I hope you remember me, we met in a huge party in Amsterdam last summer. I`m just wondering, how are you? How is the work? How are you spending your time? I want to tell you more about me and my family, my home and my country. As you know, I am living in Latvia, in a city named Riga. Riga is the capital of Latvia. I`m living there with my parents in a flat. I am studying in school, 11 grade. I am also working for my father. He has a small company, and I help him to organize some works. My mother is an architect. My hobby is football, I have played football for almost 10 years. I like to spend much time with my friends, and just hang around the city. My city is cool, there are many places to visit, and I have always a place where to go. There are many places where you can just to have a good time. I wanted to ask you some questions because I have plans for future which are linked to your country England, I am planning to go to England, because i want to educate and work there. I just wonder, do you know a cheap place where copuld I stay for a year, while I am spending my time there. Also maybe you could recommend a place for me where to work, because I will be new to your country and I will know nothing. I hope to get your answer back soon. With best wishes! Karlis 1/2 тёма Well, it has almost been 5 months since you passed away, and it has been a long 5 months. I really miss you a lot sweetie, I would do anything to have you back in my life. We were the best of friends, and I miss that more than anything. I miss meeting you in the morning before school, I miss meeting you at your locker, I miss going to get your oil changed with you, I miss cruising down Broadway chasing hot guys, I miss us just plain out spending time together. And you know what I miss the most Charity, the way you used to say "Scotty!" No one could say his name like you did. My life just can't go on without you sweetie. You were the one person who didn't look upon my family as bad people, even when my family has made mistakes. You didn't care about what happened in the past, you still wanted to be my best friend. I love you very much for that Charity. You were basically the only supportive friend I had. And now the only support that I have is your voice in my head. Charity, I would do anything to just give you a huge hug and tell you that I love you very much. I want you to come back so bad, nothing is the same without you, NOTHING!! I do see your mom a lot though, I am really worried about her Charity, please watch over and don't let anything happen to her. I don't want to lose her, she is basically my connection to you, and she knows exactly what I am going through. Summer has gotten really big. You would be so proud of her. I was over at your mom's today, and Summer can take steps now with your mom holding on to her, it's so cute. But I will tell you one thing, Summer has got to have the cutest, fattest cheeks that I have ever seen. She is adorable! Your mom also gave me your lucky stone from Itasca State Park, and a ring that you had bought. I also received the picture of you with Aerosmith when you were younger. You were cute, but then you always have been. Your headstone is very beautiful, just like you. I couldn't wait for them to put it in, I even skipped 6th hour to come out and watch them put it in. But you are very well worth skipping school for. But don't worry, I didn't get in trouble for it. Well Charity, I just want to let you know that not one day goes by without me thinking of you. I think of you night and day sweetheart. I want you to know that I love you very much and miss you tons. I can't wait to be with you again. See you when I get there sweetie.
