The driver and I went back and forth for about three minutes until Greg started doing these hand motion things . First he motioned like he was eating and then he did the ' make your eyes slanty thing ' like in the picture of the basketball team . I was smacking his arm , thinking ' OMG , I ca n't believe he did that ! ' The cab driver just smiled and said " Oh yes .

Question: Why would Greg make gestures with his eyes ?
Answer: He was trying to get the driver 's attention .He was trying to get motion in his hands .He was trying to wake his eyes up .He was making a joke .
