How about you? Do you think I should be careful because I called skipping breakfast "a return to normal"? What happens when I fail to be careful about expressing my observations? Get jumped by people who urge you not to make normative statements because the possibility of you getting anecdoted to oblivion gives them anxiety?
I think "careful" here is an idiom, it's not that there is some danger. You are not giving people anxiety.
I was merely trying to remind you that healthy people's food habits are varied. So that you remember it for yourself.
I'm not claiming to be right either. I've definitely been guilty of pushing my own stuff on others. We all do that. It's easy to do. So, humility is a good thing.
I think you might have some kind of hangup, sir. You're reading hostility where it doesn't exist. I've been there too. If it's tiresome, I hope you manage to get some rest.
