Task: Question Answering
Input (English): Passage: I planned a great party , but then my family had to go out of town the same night , and I had to go along with them . This was bad luck . I now had to cancel the party .  I did n't want someone showing up when none of us were home . That would be embarrassing and very inconvenient.I decided to make a post on my Facebook page as well . I explained why the party could n't go on and said no one should come to my house .  I think all of my invited guests are on my Facebook friends list . I really wanted to have this party , but there was no way I could this weekend . I 'd have to try again another time when we did n't have any other big plans . Question: Who were they afraid they had forgotten? Option1: Family. Option2: People not on facebook.
Output (English): People not on facebook.
