Steve hangs out in the bad part of town, and he loves to drink beer. He is often seen gesturing violently with both hands, as he talks in a loud voice, even though no one else is nearby. Sometimes he repeats himself three or four times. Although police officers routinely lock up people who drink as much as Steve does, and walk around talking to no one, they always leave Steve alone. What is Steve doing while he gestures with his hands?
Steve is wearing a wireless headset. He is talking on his mobile phone.
