【明報專訊】A FEW MONTHS AGO, I posted a photograph of myself on Instagram. I was quite fond of it as I had just learned how to create four of me sitting together through the visual tricks of the photoshop app. But what I did not anticipate (預料) was that I got many comments of friends and strangers ''reminding'' me that I had to observe social distancing rules, because the four ''me's'' were seen sitting quite close to one another. It was all a good joke, of course. Yet this incident has been part of what has been called ''social media shaming'' related to what should and should not be done during the COVID-19 pandemic.
