What gets me as a non-native speaker far more than "a vs an" is the "a vs the" conundrum. I still don't quite get when something needs to be "indefinite" and I've been speaking English for close to forty years. My native tongue lacks articles altogether and it's soo bloody hard I feel hopeless I'll ever master them fully.

This one time I was at a company get-together and the CTO, whose son was just born, received some Peppa Pig merch.
I exclaimed (in English) "Peppa Pig is the shit!"
The HR lady stared at me as if I killed her father with an accordion.
