Radio Podcasts hi, it's Laura and it's late on Saturday night as I'm recording this.
And earlier today I interviewed and had the honour of speaking to some really amazing families.
Four families in this country who believe that their children lost their lives after taking part in viral challenges on the social media platform TikTok have taken the big step of suing the company in the United States.
I spoke to them today as they prepare their legal fight suing TikTok for the alleged wrongful deaths of their kids.
They've accused the tech giant of having no compassion.
The the lawsuit was filed in America on Thursday and it claims that Isaac kenny who was 13, Archie Battersby who was 12, Julian Jules Sweeney and Maya Walsh who was 13, all died while attempting the so called blackout challenge.
Speaking to the parents was so moving, not least because the deaths of their children all came as a complete shock and surprise.
They told me what it was like in the moments when they realized that their children had passed away and how their fight for the truth to find out what happened has been thwarted, as they see it, by the company TikTok itself.
TikTok have said they prohibit dangerous content and challenges and they say they've blocked searches for videos and hashtags relating to particular challenges that the parents say is linked to their deaths.
It's an incredible story, frankly, a story I'd rather we didn't have to tell.
But it's a story of our times, social media, how it can be fun, it can be great, it can bring people together.
But sometimes, and all too often, the effect it has on society, on families and all of us, can be devastating too.
And it also gives you a sense of how families find themselves alone and then sometimes find each other united in a fight for the truth and a way of trying to share their stories so that no others find themselves in the most painful and upsetting of situations.
