We have heard some great stories about fan behaviour during Euro 2016 but this one is our favourite.
Prior to their match on Saturday, Wales and Northern Ireland fans gathered on the streets of Paris.
David Watkins became seperated from 13 year old son David and was frantically searching through the crowds for 20 minutes.
Welsh fan Jason Pocock told Wales Online that he spoke to the boy and he said he had lost his dad and was clearly upset about it.
I then turned to the crowd and asked everyone to sit down because he had lost his dad.

"This message was passed back through the fans and within seconds there were thousands of Welsh and Irish fans kneeling on the floor. I asked the boy if he could see his dad and he said he couldn't, so I asked what his dad's name and then the chant started.
"Within a minute there was a bit of noise from the back and David came though and the place went wild! Beer was thrown in the air, everyone was jumping and celebrating.
