Whatever makes you more hopeful

last night I had trouble sleeping but I dreamed I went to take my grandmother on my fathers side to the bus station, the family dog came along too, it looked like the race the Marmaduke dog is, in any case my grandmother was going to get an operation, before she got on the bus she asked me if I thought she should have the operation, it seemed to me the operation wouldnt make much of a difference so I told her she should go with whatever makes her more hopeful...
