I ' m waiting patiently till the 21st . Though i was home just last week , i miss home already . I did n't get to see my friends last week because i was there on business for just a day . I did n't have time to go out with my friends because i spent the entire night at home with my family .

Question: What may be a reason for them missing home ?
Answer: They had missed their family .They are lonely where they live at now .They have n't seen their friends in a while .None of the above choices .
