I was walking down/up/along a quiet street with my friend when we heard a very loud noise.
When her pulled me I had already static. (Não entendi.)
When we looked at the next, a scare, (Não entendi.) a bank robbery .
The robbers ran into the bank, (Falta alguma coisa aqui.) had already broken the glass.
I quickly called the police and described the situation, my friend didn't know what didi (? what to do?), crying and laughting at the same time, he was so nervous.
The police arrived after 15 minutes, unfortunately the robbers had already escaped.
They asked us about the looking for criminals (?), but we couldn't help them, because the thieves were in masks, we only remembered their heights and the colors (Falta alguma coisa. As cores do que?).
Some time after this, I was watching TV at my job and I saw the same gang being arrested, and put in jail.I was much more quiet. (Quiet = calado. "I felt better"?)
Every time you write, you learn something. Do not let mistakes bother you. Use the mistakes to do a better job next time. Good luck!
