Bad Answer Bad Ending

Hi guys. I want to tell you some story. Alright. Let’s begin.
One day my dad and I were walking. That day  I went to hospital for my routine control. When we were walking, I saw a little place that they sold bagel. I asked my dad that can we could get some bugels. He said me ” No. ” but I insisted and insisted. Later then my dad said “Are you sure about your decision?”. I said ” YES! “. “Is it your final decision?” asked dad and I said ” YESSS!!!! “. We started to walk to get some bagel. My dad took 2 for me but he didn`t get any. I ate them all. My stomach was full of bagel. I said my dad “Why did not you want to take?”. And he said ” You`ll se later on.”. Tomorrow I had some stomach ache. I go to my dad andd say the situation. My dad said ” It should be a lesson for you. Don`t get nothing from the place/ person where/who you don`t know.
