They really just suck at their mother tongue.
There was for instance this kid I knew. His dad was Icelandic and his mom Chinese. And the funny thing is this. A lot of people will use what we call "slettur" which translates to spills as in you spill in foreign words into your sentence and this is common among almost everyone. But this kid was basically doing the reverse and spilling occasionally Icelandic words into his English sentences when I would speak to him in Icelandic. And the really funny part was that you'd think his lineage would mean he'd speak Icelandic and Chinese but actually he speaks very poor Icelandic and Chinese and only speaks English while studying Japanese.
