Doctor ; What's the matter with you , Ba?

Doctor; It must be something you ate. Are your Mum and Dad OK?
Ba; Yes. They're fine
Doctor; What Did you eat last night?
Ba: We ate fish,rice and soup. I also ate spinach, but my Mum and Dad didn't
Doctor; So it was probaly the spinach. Did your Mom wash it well?
Ba ; she didn't wash it. I did
Doctor; Spinach is very good for you, but you must wash it carefully. Vegetables often have dirt from the farm on them. That dirt can make you sick. I'll give you some medicine to make you feel better
Ba; Thank, Doctor.
