Germany VS Portugal

I'm very excited about this match. I think Germany is a strong team but Cristiano Ronaldo is one of my favorite players... What do you think?

Manga suggestions? I have been practicing my reading skills by reading Momotarou and other old children's storybooks, but they use words and expressions that, according to my Japanese friends, are not used anymore. I would like to practice reading hiragana and, ideally, kanji with furigana. Stories like Death Note and Nana interests me. But I think I should start with stories that are easy to understand. What manga titles should I read?

How do I answer a question about possession in Japanese? I understand that: "This is not my umbrella." in Japanese is: Kore wa watashi no kasa dewa arimasen. Is there any way to say: "This umbrella is not mine." in Japanese, starting with "Kono kasa..."

On Nihongo Study きののよる　わたしの　えいごの　がくせいは　けっせき　です　だから　とても　いそがしいでした、　そして　わたしは　日本ご　を　べんきょうします。　わたしは　how to say "I think so too!" で　にほんご　が　べんきょうしました。　わたしが　”わたしもそうおもいます”と”そのとおりです”　learned. わたしが　にほんごは　とても　むずかしい おもいます、　だから　いつも　わたしの　sentencesは　wrong とincomplete. I can barely finish my sentences in Japanese. Recently, I discovered my weaknesses: 1. Reading: especially in recognizing kanji characters, and katakana. And I still don't understand how I should place spaces between the words, because sometimes I cannot recognize how Japanese use spaces. 2. Vocabulary: I need to improve in this area before I can move on to grammar. にほんごStudyは　とても challenging, それから　がんばります！ (Corrections/Translations/Explanations are very much appreciated! ありがとうね！)

"そうか"　"そうですか"　"なるほど"　"わかります"? What is the difference in the usage of these expression? If you could give examples sentences or situations, that would be awesome. Thanks! :)

A letter he will never read. あなたが いなくて さみしい｡ わたしたちは とおく はなれて いる… しうがない。 まつわ…ろして、まってる よ。 I am trying to say... It's lonely here without you. We are far away from each other, but that's just how it is. Even so, I'll wait for you, and I hope you will wait for me too. I'm not sure if this is correct. (^.^)
