Dear Fahad,
We miss you too! I'm glad to hear your classes are going well.
Lately, I've been playing games with my little brother, when I'm not too busy with my classes.
Next summer I will be going on a lot of hikes with my family, looking forward to it! Thank you for getting back to me.
Your friend,

Usually, in a conclusion, you wrap up what you have been writing about the whole time. So, a conclusion is basically a summary of the whole text. You can introduce new ideas for the reader, but it is usually inadvisable. In a couple of sentences, you should finish your text, referring to the previous paragraphs and just wrap it all up nicely.
