Probiotics<br>My stomach was burning for several days. And I had trouble eating any kind of food. So my dad bought me a probiotic drink made with fermented cabbages. It tasted terrible. But it quickly helped my stomach.
The writer is not the dad in the story.
The writer says "my dad bought me a probiotic drink" - so the writer isn't the dad in the story. Not sure how the model missed that; maybe because a dad is mentioned...
