What are the odds???

This morning Landon wanted to let his balloons that he got from his birthday go up High into the sky, so Daddy bundled him up and took him out to the porch to let them go, he was so excited, once he did just that, they went really high up into the sky, we all watched them from the window for a few minutes, then all the sudden they started to drop back down (it was raining) so we are sure that it why, but what are the odds of them coming right back down into our neighborhood? It was so cute, cause I looked at Landon and I said "DO YOU WANT DADDY TO GO FIND YOUR BALLOONS AND BRING THEM BACK HOME?" and his reaction was "YA!!!!!!!!!!!!!!!!!" It was the cutest thing ever, John went around the corner and there they were, so he brought them back home and Landon was so excited, Daddy shook off all the water from the rain, and they floated right back up into the ceiling of our house. A little while later, Landon let them go again, .....IT WAS SO FUN TO WATCH HIS REACTION!
