Reflect on this – The mouth can already have a sweet/bitter/neutral taste and how it perceives the taste of food could depend on that. My question is – if the mouth is already bitter, will it be fully able to grasp sweetness in the food? Or is the food actually bitter?

If you are satisfied with your answer, consider this – what is perception per say? Is perception really reality or a segment of it? What are you more afraid of – being a fool or being perceived as a fool?
