Whenever someone said the word "Grades" it reminded me of grapes and suddenly I would start craving them. I guess they both sound similar.
Also, when I was little about 5 or 6, my dad had chocolate and told me to share it with my sister. Since then, whenever I hear the word share or shares it reminds me of chocolate.
