1. You find Scrabble frustrating because you see word opportunities in both languages.
Unfortunately, you can’t write “konstantynopolitańczykowianeczka,” the longest word in Polish, or anything using “sz” “cz” “rz” because they don’t count as words in American Scrabble.
2. You speak Polish.
For a time, you actually thought the only language in the US was Polish, because every single person around you spoke it.
