“Thank you mum and dad for throwing such an amazing party last night,” he wrote.
“To all my friends thank you for being part of a night I will never forget.”

“You are kind, passionate and caring and as a father that’s what you want to see in your son... we have had so many great moments as a father and son together like lifting trophies in all the places that I won them and for me that was always my dream.”
