Letters

Last night, I just felt like writing a letter to my friend. Although I was supposed to reply to her, I had not. I had almost forgotten it. When I remembered to write her back, I started to write as much as I could like I was waiting for this moment. It had* been a while since I wrote a letter to someone. After I was done, I just thought back on how I used to write letters to my best friend. I didn't know how she was doing, so I wrote her a letter impulsively*2.

Today, I visited the post office. I imagined my friends' countenances and their surprise. They might notice my yearning for them. A letter is very peculiar, it gives expectations and pleasant feelings(*3) to both giver and taker.
Even though technologies have developed more convenient ways to contact people, they will never replace a letter.

* "has" isn't wrong but the rest of the note is in the past tense.

*2 Not quite sure what you're trying to say here. I think you could also use "spontaneously".

*3 Again, I'm not sure what you're saying with flutter.

I liked this a lot! I'm also fond of writing letters and also often forget to do so.
