Unfortunately social media rarely shows the full picture.
Yes, this girl was missed. But it was noticed and very quickly rectified - within about 15 minutes.
It happens regularly due to the excitement of the kids and they are all moving about and as in this case, almost always rectified within minutes. But most parents just see it for what it is - an error.
The only option is to have them all line up and step up to receive their medals, but when dealing with young excited kids, that simply is not feasible.
The worst part is one of the people in gymnastics Ireland who had nothing whatsoever to do with the event and who was not at the event, got named as the person giving out the medals.
I think this family made a big issue out of nothing and by passing the video onto a well known person, they knew it would be shared, but possibly did not realise it would go viral and it now seems they are getting targeted and some people will possibly target their kid.
Frankly, they should have accepted it was an error and accepted the genuine apology from the official especially after they saw it was rectified so quickly.
