Before the days of Facebook, I remember receiving dozens of postcards throughout the summer from my friends wherever they were spending their summer vacations. Likewise, I was sending them postcards as well and it was a great way to say I'm thinking of you. They meant so much to me to where I still have a shoe boxes filled with them. I think a handwritten "just because" note is still something so special and important to still do for those you really care about.
It means so much to the person who receives it, that you simply took the time.
I hate to think that letter writing is a lost art form, but that's where I hope we'll all disconnect from our electronics and slow down for a moment. Why not write a letter to someone who really needs the extra-pick-me-up. You'll never know how they kept your beautiful note in shoe box years later.
