My lunch I had with my friend Gary (1) did not go very well. For one thing (2) he said he would come to pick me up (3) at noon.

When he came back to get me, he was mad, at me. (5) "I couldn't find your doorbell," he shouted, "because there was no name tag on it, so I had gone (6) all the way home to get my phone just to text you!" (7)

"That's right," he replied __________ (8). "If you had been waiting downstairs, I would have had to not go through all of this." (9)

"But you're the one who left your phone at home," I countered, "and you always text me when you get here. Never have you asked me (10) to wait outside for you."
