I think I used a mental shortcut and assumed their reason was due to frustration because a fairly common context for sentences like the one in the comment I replied to is due to reasons of disagreement or dislike due to opinion, quality, lack of information, or some other reason.
I got COVID after taking all precautions because my father didn’t wear a mask and took it home. I was sick for a month. I only left my bed to use the bathroom or eat. I literally slept the rest of the time. I probably should have gone to the hospital because I could hardly stay awake even just to eat. I remember waking up one day, and just knowing that I was recovering.
Recovery was hell. I couldn’t taste, or smell anything. I had awful flu like symptoms. I was lethargic and I could hardly walk. It took two weeks to feel functional, and for three months my sense of taste was completely fucked.
