Inferring doesn’t mean the same thing as implying. They’re kind of complementary, like borrowing versus lending.
The OP may have been implying something, but it looks like you’re inferring something (which may or may not what they’re implying; I don’t care enough to parse that out).
While kids are now more likely to be diagnosed with ADHD due to increased awareness and better diagnostic methods, this can also lead to an interesting “reverse echo” effect where their parents have a sudden realization that they’re ADHD too.
Hearing about the symptoms from a doctor talking about your child can be an eye-opener that stuff we called “laziness” and “being too sensitive” back in the 80s might have a better name.
