こんいちわ！日本語を学び始めました。本で学んでいません。インターネットで学んでいます。

Konnichiwa! Nihongo o manabi hajimemashita. Hon de manande imasen. Intanetto de manande imasu.

Hi! I've started to learn Japanese! I'm not learning from a book. I'm using the internet.

I really like Japanese, and find the grammar really cool. I've been learning for about three or four days now, so I obviously still have a lot to learn.

如何して手紙を僕に送りましたか。
Doushite tegami o boku ni okurimashita ka.
Why did you send me a letter?
(Lit. Why letter [direct obj. particle] I [indirect obj. particle] sent [question marker])

It might look weird at first, but once you get used to it, it makes sense. So, if you liked the little you saw of the Japanese language in this post, perhaps you'd consider learning it!

Wish me luck!
さようなら！
