['When I cross a major street I am always worry about getting hit by a car. I try to be careful and only cross at the crosswalk but I am still nervous.']
Those are good preventative measures. I assume that you always look both ways as well?
Every time I walk across a major street I am afraid I am going to be hit. I use the crosswalk and look both ways but I keep thinking someone will not stop. I wish I didn't worry so much.
