I included this in a bill I was paying, which had "issues," for the girl that was helping me.
I hand wrote a brief note about what I do, inviting her to join us if she would be interested in paper crafting. She sent an e-mail thanking me for it, and more, and saying how I'd made her day!
Well, sure enough, sending her note to me had made my day, in return! I love "feel goods!"
