Was it a Sign or just a Coincidence?

So as you all know our little man Jack has been getting check ups and such on his heart, and just this past week we were told that there might be issues. This was news to us as this whole past year we had been told that things were great, yes he had holes but they were healing on their own, and in fact 1 of the 3 was getting really close to closing. So we were shocked when we went in and were told that we were going to have to do some more testing to see what is going on. Well I left the hospital in a sea of emotions, which I'm still trying to figure out which one to focus on, but the other day I was going through a drive through at a convenience store to get a soda, when the guy helping me -who was probably around 17-18 - asked if Jack had Down Syndrome.. he could see Jack sitting behind me.. I told him yes and the guy went on to tell me how he had a 5yr old brother with Downs and how much he loved it all and just little stories about his brother.. It was so great to see how happy this boy was he was just a big smile from ear to ear.. well after he handed me my drink he asked about Jacks health. I told him we had thought everything was fine but that we were going in to look at his heart. He said that his brother had to have open heart surgery at 4months old but that he is just doing great today he said his brother is probably close to the same size as Jack.. That just so freaked me out I mean I know its pretty common for children with Downs to have heart issues which many require surgery but it was just the timing and everything... But anyway the cutest part was the boy asked if he could give Jack a sucker... which was so sweet but my little guy is a VERY picky eater to say the least and the look on his face if he was to try a sucker would just be way too funny...So we had to pass but just the actions of this boy were very sweet.. It was a good moment.
Our countdown to the ECHO is 3 more days... Keep your fingers crossed and our little Jack in your prayers...
