they both have such lovely colors, and one would expect them to taste or smell really good too.
as a kid i remember biting into a crayon, only to find that it tasted like wax. the Crayola crayons prove to me the most deceptive, because they have such descriptive names, and they all taste the same. slightly waxy, and not very tasty.
and while i never tasted nail polish (i think it would be slightly more toxic than crayons) it never smells like the color looks like it should, but just smells like nail polish.
i was in a clothing store, paying for clothing, when i saw a nail polish labeled Espresso Yourself. the color was such a lovely brown, and really looked like chocolate. i uncapped the bottle and sniffed, only to be hit with the usual nail polish smell. "ugh, smells like nail polish" i muttered to myself. i placed the bottle back on the rack, and looked up, only to be greeted by the puzzled face of the cashier. i bet she was wondering what i expected it to smell like.
i have a nail polish that's a deep purple. that too proves to be disappointing, because it doesn't smell anything like the plum shade that's found in the bottle.
