Have you ever released a balloon into the sky?
When I was a little girl my dad would go hunting up in northern Canada for weeks at a time. My sister and I would get so sad, we would cry and cry.... I mean not talking to your dad when you are 6 years old for 2 weeks sounded like the worst thing in the world. How would we survive? I could tell when looking at my mom that her heart would break for us, she has two little girls who just wanted to talk to daddy but he was out hunting, what to do? We started writing messages on balloons and releasing them into the air. My mom swore that dad would see them and get our messages. She told us he would know we were thinking about home while he was gone. Dad would come home from his trips, and the first question would not be, "how was hunting, or what did you get?", but rather, "Daddy, did you see our balloons we sent you while hunting?" The answer was always yes. It just made me the happiest little girl and I truly believe still to this day my dad would get the balloons I sent him.
Something about balloons floating away into the sky has magic. For which ever reason you are releasing them, if it is someone here on earth or up in heaven, they definitely get the message.
