So in my story a girl is hitchhiking east to live with her boyfriend. One of the drivers she's hitching a ride with is asking her why she's going east.
"Willow decided she didn’t want to tell him that she was going to live with her dorky boyfriend, so she decided on something more ___ / she decided to give a more __ answer"
'Moving,' she answered tersely.
I'm thinking "general" or "vague", but I don't know if they're exactly describing what I'm looking for. I'm not 100% sure a phrase would work here, but I could always rework the sentence if it fits the best. I need an adjective.
