My vocab-recall is identical! I can hear the cadence of a word and usually get a near-sounding word /phrase. My family thinks I'm crazy when I try to explain it. I STILL get made fun of for a highly-competetive game of Taboo circa 1995. In the rush to get my sister to say "race horse", I shouted out, "Never shoot a ______ _______ in the mouth!"
...I meant, "Never look a gift horse in the mouth." No one believed me that shoot and look are similar because of the double O's. Instead they held tight that I had indeed cheated in school.
