You can tell second-language speakers because they know when to use "its" and "it's".

Thanks to having kids, I ended up reliving lots of details from my own K-3 education and one of the things I clearly remember was coming up with my own mnemonic of remembering its vs it’s by comparing those to his vs he’s.

“they” as a non-gendered singular pronoun dates back hundreds of years.
