For instance, they always hang around with the same few people, they have a strange look in their eyes, and because they are sensitive, suspicious and always worried that they are being followed, they generally don't speak much with other people, and are afraid to look them in the face.
例如他們總是固定幾個人在一起，眼神很詭異，由於敏感、猜疑，擔心被人追蹤，通常不跟人說話，見到人頭低低的，不敢正視對方。
