Pajamas are the most comfortable of all! It looks like Mom had an adorable idea to have everyone wear their matching PJs on Christmas Day. Dad on the other hand...he had a different idea. I mean look how much fun the rest of the family is having and Dad just REALLY stands out as a lone wolf.
The kid's expression is indeed priceless. The photo says it all that he doesn't want mom and dad slobbering him. Who would like saliva dripping on their cheeks? It's just not right and his face is crying for help. Well, you can;t do anything about it kiddo, mom and dad rule.
