The sacrifice isn’t really wearing a mask. It’s avoiding the get togethers and in person events and having people forget about you and move on with their lives while you’re still cautious. You could argue that these are small things too, but it’s a pretty big change for most people, and while they claimed this was a “big sacrifice” that’s just a figure of speech… They didn’t claim it was something they couldn’t do or weren’t willing to do, just that it sucks… Which it does.
