Awww...I was hopeful you would tell me they just decided to go on Open Table. No worries - I thought the same too until I went to get a reservation.
Btw, its good to note that larger groups have more difficulties with reservations. None of 9 people 6 months out but I was able to get one for 8 people. Also, the time of the reservation matters. If you are having difficulty, play around a little. 2 people have more options than a large group.
