Kindness of strangers

We didn't take John out to eat for many years.  It was mainly because of his never-ending seizures, but also because of his behavior.  Over the years his seizures have decreased and we've just gotten used to the behavior.  We don't even think twice about taking him out anymore.  Of course we take him to "noisy" places and it can sometimes still be a challenge.  Such was the case last night when we took him to a busy local pub.   He was a little more rambunctious than usual and I felt a little sorry for those around us.  He would make a lot of loud noises and bang the wall or table on occasion.  We were struggling a bit to keep him under control while waiting for the food to come (and it took forever - typical of this pub).
Once the food came he ate some of it very quickly and then Yoshie took him to the car to finish eating while I waited around to pay the bill.   The waiter came over and told me that someone had paid the bill for us!   Wow.  That has never happened before.
I went to the front and looked around to see if anyone was looking at me.  I wanted to sincerely thank whoever had done this.  I couldn't pick any one out.  I went and told Yoshie and she came back inside and asked the manager.  Apparently some nice man had just noticed our struggles and wanted to help out.  He just left a message saying "Merry Christmas" to us.   He was already gone and didn't leave his name.
We've been lucky to get a lot of support over the years from family, the medical community, the school system, etc. but never from a perfect stranger.  It kind of shell-shocked us.  Yoshie was in tears.
Thank you to whoever did this for us!  And, we will do the same for others if ever in a similar circumstance.
