A Bad Experience

I can remember a day when I was five or six years old age, that when I forgot that my mum had told said me that I had to take the school bus to come back home because she couldn't pick me up. Then, when I finished school the class day, I waited for her in at the school gate of the school. Unfortunately when all of the buses had left the school, I remembered what my mum told me. Then I started to cry, cry and cry until a teacher picked me up and returned me to the school.
The scary  fear/anxiety of my mother when I didn’t get off in at the bus stop was horrible!!

I can remember a day, when I was five or six years age old, that where I forgot that my mum said to me that I had to take the school bus to come back home because she couldn't pick me up. Then, when I finished the class (school) day, I waited for her at the school gate in the gate of the school. Unfortunately, when all of buses had left the school, I remembered what my mum had told me. Then I started to cry, cry and cry until a teacher picked me up and returned me to the school.
The scary scared face of my mother when I didn’t get off in at the bus stop was horrible!!

I hope your mother was fine when you got home!
I hope this helps.
