Which sentence in this excerpt from Leo Tolstoy’s The Death of Ivan Ilyich suggests that Ivan Ilyich felt his family and friends didn’t understand him and neglected him?

He looked at his partner Mikhail Mikhaylovich, who rapped the table with his strong hand and instead of snatching up the tricks pushed the cards courteously and indulgently towards Ivan Ilyich that he might have the pleasure of gathering them up without the trouble of stretching out his hand for them. "Does he think I am too weak to stretch out my arm?" thought Ivan Ilyich, and forgetting what he was doing he over-trumped his partner, missing the grand slam by three tricks. And what was most awful of all was that he saw how upset Mikhail Mikhaylovich was about it but did not himself care. And it was dreadful to realize why he did not care.

They all saw that he was suffering, and said: "We can stop if you are tired. Take a rest." Lie down? No, he was not at all tired, and he finished the rubber. All were gloomy and silent. Ivan Ilyich felt that he had diffused this gloom over them and could not dispel it. They had supper and went away, and Ivan Ilyich was left alone with the consciousness that his life was poisoned and was poisoning the lives of others, and that this poison did not weaken but penetrated more and more deeply into his whole being.

With this consciousness, and with physical pain besides the terror, he must go to bed, often to lie awake the greater part of the night. Next morning he had to get up again, dress, go to the law courts, speak, and write; or if he did not go out, spend at home those twenty-four hours a day each of which was a torture. And he had to live thus all alone on the brink of an abyss, with no one who understood or pitied him.
