Oh I love a flippant answer that has no argument, it proves you know you're wrong and at the very least cannot support your argument so instead you insult like a child.
Oh I love it, it's your "mother language" and yet you can't form an argument as to why our how I'm wrong and yet I've proved with evidence how exactly you are wrong.
Nope not at all, I've proved your wrong about the idiom and your ego won't let you admit that simply speaking a language doesn't make you an expert in it nor does it in fact make you an expert in the idioms thereof.
Sure, I'd love to speak to your mother, get her on here in sure she'll be super proud you're arguing against a dictionary.
