Context: It just did n't seem right that Bob & Donna should ignore the one person above all who is responsible for their being together . The more I thought about it , the more annoyed I was with them for being so rude . So I emailed them two days before the party and said their not inviting Margo meant that I was in a delicate situation , that it just did n't seem right and could n't they just invite her to have a cocktail beforehand ? My thinking was they 'd see the light and go ahead and invite her to dinner .

Question: Why did they not invite Margo to dinner ?
Options:
0. They thought she would not enjoy the restaurant they chose so they excluded her
1. They had had a fallout with her recently and felt awkward about things and so chose not to invite her
2. They thought that she always ate too much at restaurants and so they were anxious to invite her because of her habits
3. They had a strict budget and did not have enough money to invite everyone they wanted to
Answer: 1
