This is really hard...
The longer and more complicated the item, the more likely it is to be true... So, that comes down to the restaurant (which is crazy enough to be true) and Afrikaans. Everyone knows that people speak Afrikaans in South Africa, but not everyone speaks it - many only speak English with a distinct South African accent (I have a lovely friend here in Wyoming who is from your country.) Despite the fact I feel there is Dutch blood in you, it doesn't mean you speak that language...

So, I'm going with 5. You did not grow up speaking Afrikaans.

Fun contest anyway.
