I'm not completely sure what that means but I'm positive that if I send mail (event A) the probability that I will receive mail (event B) is very great! In fact since I started my mail more magic postal project, I've had so much happy mail! I've even had some spontaneous mail from folks that have just heard about my love of all things postal! Just today I received a hand written note and a fascinating article about receiving mail on the trail during a bicycle adventure. This note and story made my day!! Thank you so much, postal pal!
I encourage you all to continue your quest to mail more love. We really can stamp out despair one letter, postcard, note, card and package at a time!
Send more mail, people. It's mathematically proven to be magical!
