If I see Santa, I will hug him straight away, and thank him for his generosity to all people especially to kids. I would tour him around my house, and I would give him some cookies.
I will touch his face and his long white beard and ask him to have a selfie with me and my family.
I will ask him this question that's stuck in my mind when I was a kid and up till now What it feels like, to be Santa Claus?"
