Ex-boss: "Okay but how come do "L, C, B and B" can't talk like you? Even they can't write in good English grammar and whatnot? I thought you all guys are the same."
I really hate that comparsion.
Next time that happened, just say "So-and-so (a CODA) can sign so why can't you sign????"
My former sister-in-law said "You drive!?". No wonder, I didn't really like her ever.
