This is a common enough occurrence. You’ve likely seen it without even realising. It boils down to the act of pretending you’re still on holiday for your social media followers, prompting the envy of your peers over your seemingly three-week-long trip to Mexico. In reality, you’ve been crammed on the Central line, sorting laundry and fighting over the last Pret sandwich since you got home 15 days ago. The lie can take various forms. Perhaps it’s the ‘photo dump’, a 10-slide long gallery of holiday highlights ranging from candid bikini photos to hiking at dawn wholesomeness. It could be a wistful #takemeback snap — of which there are close to 15 million on Instagram (can we just retire that hashtag once and for all, please?). Or, in my case, it could be a straight-up lie, a falsehood created to ease myself back into the reality of normal life, retaining the glossy allure of a far-flung holiday for my digital self only.
