I love the idea from the beginning! I literally haven't mailed anything in ages, I have to say I also only receive love letters from my bank sending those loving statements of numbers. Enough of that I say!
My dad is my hero, and even though that is not really a secretly admiration, I also know he used to write to my mom all the time before they were married. Mail was a thing. He kept all her letters. This website inspired me to send a little something to him. It was actually really awesome that the day it arrived I was right there! Can't describe the feeling of seeing his face when he read it ! It just lit up the entire room. Worth spreading some love around!
