My father sent me a photo of a letter I wrote for his birthday when I was a kid.
human
Oh how sweet! What did it say?
human
I wrote about how much I appreciated him picking me up from school everyday and helping me with my homework. So adorable to read it!
human
I love finding treasures like that! 
human
Yeah, I'm glad he kept them because it's always amazing to find it later in life.
human
I hope that I am able to share such nice things with my own kids one day.
human
Me too. I will keep every little drawing and letter they make me. It's worth it.
human
I really enjoy that too!
