Westlife singer Shane Filan, who lost both his parents to cancer nine months apart, says he still goes to call them.
Now an Irish Cancer Society ambassador, he wants to help raise money for the charity.
Friday marked Daffodil Day - the first in-person fundraiser in two years due to the pandemic.
Shane says he feels this is keeping his parents memory alive.
"I think we're all still a bit in shock and still getting used to it.
"I still go to text him and ring him, or call my mum.
"I'd love to go now and have the cup of tea and tell my dad that news - we're all, as a family, still processing that."
She says it's still very difficult.
"People say 'It gets better and better', but it's not really getting that much better at the moment.
"I think it's still very, very difficult.
"And I think it will take time, obviously, and you've got to process it as best you can.
"Today I'm kind of smiling a little bit, I'm thinking of them, and every time I see a daffodil I think of them.
"There's something that I can kind of process it a little bit in a happy way, to know that raising money for the Irish Cancer Society my mum and dad are helping me do that.
"So it's keeping their memory alive in a happy way".
