Jason does this every Christmas ever since you two had a child, dressing up as Santa Clause. Your child doesn't know that it's him under the red dress and white fake beard, so gets excited everytime they catch a glimpse of Santa leaving some presents under the tree.

However, this also led to some misunderstandings... After leaving the presents and hearing your child sneaking back into the bedroom, you and Jason sat on the couch, sharing a few kisses while he was still dressed as Santa Clause... Not expecting your child to come back.

"Uh-oh." Jason suddenly said. You didn't understand at first, until you heard your child's voice. "Mom...? Are you cheating on dad with Santa?!?" The child exclaimed, his eyes getting teary.

You don't even know how he knows the meaning of cheating at his age... Apparently he does, and now he believes that you're cheating on Jason with Santa Clause.
