Do all people generally like to have hard and soft tastes and mouth-feel equally balanced all of the time? No. Some people like sweetened lemonade (soft) or sweet tea (soft), coffee with ample cream and/or sugar (soft) while others prefer their lemonade lemony (hard), their tea unsweetened (hard), and their coffee black (hard). At different times we may prefer a vinegar-based salad dressing or marinade with some sugar added (balanced) or a vinaigrette with just vinegar, lemon, and salt (hard and unbalanced), or a creamy sweet poppy seed dressing (soft). In other words, our own preferences can change and adapt.
