Send someone a real letter

I sent my mother-in-law a real letter. She is 93 and still lives on her own. Her year has been a tough year and I used this opportunity to send her some love and let her know that her family from far away, thinks of her often.
She is the most caring and selfless person I have every met. I realized while writing the letter, that I do not do this often enough. Putting words to paper and emotions to words, it a moving experience. It is something I will make a part of my regular day.
