The 15-year-old girl who comforted a blind and deaf man on a flight with sign language has spoken out about the moment that warmed hearts across the nation.
Pictures of Clara Daly signing into the hand of Tim Cook on their Alaska Airlines flight from Boston to Portland last week quickly went viral.
And while many - including Cook himself - have called Clara an angel, the Los Angeles teen revealed she was nervous she was going to say something wrong.
But Clara didn't hesitate to volunteer when a flight attendant asked if anyone on the plane knew American Sign Language.
While the flight crew did their best to ensure Cook was comfortable and well looked after, they struggled to communicate with him.
'They thought that he might need something and they weren't sure how to communicate,' Clara said.
'I pressed the call button and then [the flight attendant] came and she said "So we have a passenger on the plane who's blind and deaf, do you know how to finger spell?"' Clara recalled.
Clara said Cook first told her he would like a water and asked how much time was left in the flight.
She then returned to her seat, before an attendant came back and said Cook had asked for her again.
'He didn't need anything. He was just lonely and wanted to talk,' Clara said.
'I was thinking, "Wow, this is so cool, I hope I don't spell anything wrong"', Clara recalled.
Clara said she has found it funny that her story is getting so much attention.
'Doing something like that is just what anyone would have done,' she said.
'It was immeasurable before but it's even...what's infinity times infinity?' said Bill.
Cook himself has called Clara an 'angel', and she also won high praise from Lynette Scribner, who was seated next to him.
Scribner took to Facebook just moments after stepping off the plane to tell Clara and Cook's amazing story.
Her post and photos of Clara signing into the palm of Cook's hand mid-flight have now been liked more than 950,000 times.
'I saw this man, Tim, in Boston's Logan airport with the sister he'd been visiting...it appeared he was both deaf and blind,' Scribner posted.
'When he asked if she was pretty she blushed and laughed as the seat mate, who had learned a few signs, communicated an enthusiastic "yes" to Tim.
