Answer:
Mike's point of view is affect by his grandmother's greeting in the sense that:
B Mike realizes that something is off in his grandmother’s behavior.
Step-by-step explanation:
In the story "The Moustache" by Richard Cormier, Mike visits his grandmother at a nursing home. She welcomes him with such joy and brightness that he is, at first, relieved. He was afraid it would be one of those days when she couldn't recognize him. However, after a moment, he realizes there is something off in her behavior. He cannot put his finger on it, though. He does not know if she is just happy to be lucid, or if she has been feeling lonely:
I was beginning to feel uneasy, because she regarded me with such intensity. Those bright eyes. I wondered -- are old people in place like this so lonesome, so abandoned that they go wild when someone visits? Or was she so happy because she was suddenly lucid and everything was sharp and clear? My mother had described those moments when my grandmother suddenly emerged from the fog that so often obscured her mind. I didn't know the answers, but it felt kind of spooky, getting such an emotional welcome from her.
