I worry about him because he 's a senior in high school , does n't seem to spend anytime outside of the house with anyone besides my family . He spends his time playing video games in his room . The cat ( who will chomp on the ankles of all others ) loves him . I do n't know what she 'll do when he goes away to school .

Question: Why does the speaker worry about him ?
Answer: Because he does n't spend that much time with friends .Because he spends too much time outside of the house .None of the above choices .Because he might not graduate high school .
