Who's the last person you wrote a letter to?

I think mine was when I was about 14. I used to write to my aunt abroad. She was the youngest sister from my moms family and she was the only one not home. Usually I'd write to her around Christmas, telling her everything that's been happening. About our Christmas tree, about my grades and stuff that I was finding exciting at the time. And then she'd write back. I'd also write to my granny, just because I thought it would make her feel good.
