I just got back from buying some groceries . The man in front of me had gray hair . His fingers were all bent and it took a long time for him to write his check . He looked to be about 80 years old .
What may be a valid thing the gray - haired man was doing ?
A. He may be getting a haircut at the saloon .
B. None of the above choices .
C. He may be getting his social security check .
D. He may be standing in a line .
