Seconding this. Nobody ever says “I’ve got a touch of lupus” or “I’ve got a touch of a brain tumor.” Knock it the fuck off.https://twitter.com/fkathryn/status/972136892534808577 …
I have OCD. I might say “touch of” or something like that just because it doesn’t mess with my life in any important way. It’s just about even numbers, symmetry, etc, and I have taught myself to allow myself to ignore it in some circumstances. But I do agree with your sentiment.
