It can work. My husband is a wheat thin eater, while I am firmly in the triscuit camp. We reluctantly eat each other’s crackers when there is only one box in the house, or we don’t want to have 2 open at once because they’ll get stale before we can eat them.
I know he’s wrong - why go for the pasty blandness of a wheat thin when you can have the toasty crunchy nutty salty joy of a triscuit? - but he’s got enough other good qualities to compensate. No doubt he feels similarly about me.
