I went to an exhibition today. Initially, I planned to take the bus, enjoying music and the scenery along the way. However, there were no buses available, so I ended up taking a motorbike taxi. 今天去看展了。本来想坐公交车去，一边享受音乐一边欣赏风景的，但是没车了，最后坐摩的去的 When I arrived, I invited the motorbike taxi driver to go in with me and also asked him to take some photos of me inside. But he declined and preferred to rest outside. After I went in alone, I found that I was the only visitor. After looking at some exhibits, the staff started taking photos of me like crazy with a camera. I thought he would just take a few shots, but he kept going. I know he was documenting the visitors, but I thought it was a bit over - the - top. After I came out, I asked the motorbike taxi driver to take some photos of me outside to record my outing. 到了的时候，我想让摩的师傅跟我一起去，也想让他帮我在里面拍几张照片，但是他拒绝了，他想在外面休息。我一个人进去后，发现只有我一个人，看了一些展览品后，工作人员就拿相机疯狂给我拍照，我以为他只是拍了几张照片就好了，没想到一直拍。我知道他在记录看展的人，但是我觉得太疯狂了。后面我出去后，让摩的师傅在外面帮我拍了几张照片，记录一些我出去玩的身影。 Later, I contacted the staff on the platform and asked him to send me the photos. 后面我在平台上找到工作人员让他把照片发给我了。

Let's study a new idiom! 'He said he was sick. But I _____ a rat, because I saw him yesterday walking with his friends.' Meaning: to sense that something is wrong or suspicious
