I know it might seem strange, but I like to keep your letters.

Oh really? Why is that?

Because I want to remember the sound of your voice and the way you laughed.

That's really sweet of you. But you know, you could always just record me talking or laughing.

I know, but there's just something special about having your handwriting on paper.

I understand. Sometimes I find myself reading old letters from my parents just to hear their voices again too.

Exactly. It's like they're still here with you, even if it's just in your memories.

I completely agree. It's a way to keep them close even though they're not physically here anymore.

And that's exactly how I feel about keeping your letters. It helps me feel like you're still here with me, even if it's only in my thoughts and memories.
