You shouldn't hate things.
Dave is at a party when he's offered some cocktail shrimp by Sandy.
Dave wants to decline the cocktail shrimp.
Dave tells Sandy that he already had too much to eat and isn't feeling too great any longer, so he'll decline.
Dave tells Sandy that he absolutely despises shrimp in all forms, and he doesn't want any.
Sandy is understanding as to why Dave would not want any Shrimp and moves to the next guest.
Sandy is shocked that Dave has such intensely negative feelings towards Shrimp and finds him odd.
