One day, I went to visit my friend on a bus.He lived in another city so I went by the express way.
It was a winter morning,besides, It snowed last night so the road was very slippy as you could imagine. While I was worrying about my safety,all of a sudden, the car in front of us slipped,and hit the bars along the road,then stopped just in front of us! Our driver didn't think too much and hit the brake very hard. Thank god, it stopped just in time.
I would never travel on a snowy day.
