眨眼睛

Her answer was gruff, but her eyes twinkled.

她的回答很粗鲁，但她眨了眨眼睛。

For example, once a girl found I like nictation, she said because I through that way to attractive others eyesight and show my beauty, actually my behaviour is empty-headed.

比如上大学的时候有女孩说我总是喜欢眨眼睛，以此来显示自己长得不错，得自己很了不起的样子，其实很浅薄。其实只是因为我戴着隐形眼镜，眼睛干，不由自主的就眨眼睛了。
