<human>: Hello all,  
My friend of two years is finally moving on in life primarily because she was a foreign exchange student in the US, and I would like to give her a very meaningful letter, but I just cannot begin to write a letter to her, because either I feel, 1) I don't think it would be meaningful to write a 2 sentence letter. 2) I get kind of sad thinking about her leaving.  

Honestly, I did like her for awhile which is making it worse, but the thing is, she's going back to her country which is across waters, and while we could easily chat over facebook I won't be able to see her for quite a long time, or forever.    

So /r/relationships, how would you write a letter?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Friend is moving back to her home country, and don't think I will ever see her again, so I want to give her a meaningful letter before she goes, but don't know where to start.
