This meme originates from the 2014 Australian psychological horror film "The Babadook." The top panel shows Amelia, the stressed mother, yelling "Why can't you just be normal?" at her son, Samuel, who is seen screaming in the bottom panel. The meme is used to humorously depict situations where someone expresses exasperation or a desire for another person or entity to conform to expectations, while the latter defiantly (and often dramatically) refuses or continues their unconventional behavior. It perfectly captures the relatable feeling of frustration when dealing with someone or something that simply won't 'behave normally,' often in a self-deprecating or ironic way.
