u wake up on christmas morning and go downstairs, full of excitement. somebody is stealing all of your christmas presents. it is jesus. “its my birthday, not yours” he hisses menacingly, then runs away with all your gifts in his arms
"oh, please. you can’t REALLY be in a great mood. there are people out there who just got raises. people just got married. people are being reunited with their families right now. how dare you say you’re happy."
The equivalent of someone saying you can’t be sad because other people have it worse than you.
