I am going nuts with the sentence below. I am supposed to fill in the gap with an expression containing the word in bracket SPOT. Can someone help me complete this sentence?
"I can't understand poetry. I am afraid it is a...............(spot) with me."
I am very confused whether I have to use an idiom like "to be in a tight spot" or a phrasal verb or other. I have tried some expressions but the preposition WITH after the gap makes me think I am far from right in my guesses.
