求翻译：今天晚上九点多的时候，我和姐姐一起下楼买东西，在回来的路上，总有一种莫名的感觉。一个骑自行车的中年男子一直跟在我们的左右，我们停下来他也停下来。于是我和姐姐向反方向走，那名男子一直盯着我们。我们便拿出手机给家人打电话，叫他们下来接我们，想想这件事都后怕！是什么意思？

At around nine o'clock in the evening when I came downstairs to buy things with sister, on the way back, there's always a strange feeling. A middle-aged man riding a bicycle around has been with us, we stopped and he stopped. So my sister and go in the opposite direction, the man staring at us. We come up with mobile phones to call families, that they meet us, think about it is scared!
