It is common for people to read a word and then re-use it themselves shortly after.

Humans are very suggestible.

Can't see the original comment, is that about my usage of the "astounding" word? I am Ukrainian (not a native speaker), and it popped up subconsciously, but now that I see it it another comment – very likely I just read it, that's why indeed! Amazing

> very likely I just read it

I find myself doing it frequently. I'm even sure that's why I used indeed above after reading your comment - it wasn't intentional!
