crying at sams club

So yesterday we took a trip to sams club. Haley had her oxygen and was talking to an older man who was telling her sometimes he has to wear on of those too. She thought that was pretty cool, not that he had to wear one but that he gets it. A small old man with a cane and a heavy accent came up and asked what happen that she had to wear this. I told him she has PH. We talked for awhile, he was really effected by her and started crying, well once that happened then of course I am fighting back tears. He told me he had 3 daughters and couldnt imagine having to go through this at such a young age.  I felt so bad, I just wanted to hug him. So thankfully shortly after the emotion came he went on his way, I only say thankfully because I could only imagine what it would look like for both of us to be balling in the middle of the store.
That was the first time any one has ever asked. I didnt mind, it was kind of nice that he cared enough about someone he would probably never see again.
