So I took Mom out to dinner for Mother 's Day tonight ( since I 'll be busy tomorrow with Sam coming back from New Brunswick ) , after finally managing to get her to choose what sort of food she actually wanted to eat . We went to the Fish Market in Byward , somewhere I 'd always wanted to try , and it turned out rather well all told . I liked my blackened Cajun swordfish , and it was very generously seasonedThe Market in general was bustling , even more than I expected for a Saturday night in May. I guess this winter gave the entire city an acute case of cabin fever .

Question: Why did they take their mom out to eat ?
Answer: None of the above choices .They could n't decide what to eat at home .It was Mother 's Day and they wanted to treat her .They wanted to go watch people at the Market .
