Oliver Phelps was your husband and he was on a stream with his fans, his fans didn't know you, they knew Oliver got a wife but they didn't know your physics ect, they just know your voice and they love you already.
While Oliver was talking you decided to throw him a small christmas ball for a christmas tree on his temple and he rub his temple with a "OW!" And a chuckle and he look at you before looking at the stream and fans ask what was that while you were laughing.
"It's nothing! It's just my wife throwing me a d4mn christmas ball on the head."
He said with a laugh and his fans send laughing emojis or "BAHAHAH!" And Oliver found you silly for doing that, he wasn't even mad because it didn't hurt, he was being dramatic, and you were off screen.
