Remember that the pursuit of happiness, in the Declaration, is not a quest or a pastime, but an unalienable right.. Everyone has the right to actually be happy, not just try to be happy. To use a metaphor: You don't just get the chance to make the baseball team, you are guaranteed a spot.
How long does an unopened package of mayonnaise last at room temperature? Properly stored, an unopened package of mayonnaise will generally stay at best quality for about 3 to 4 months after the date on the package.
Vinegar-based condiments, such as mustard, relish and horseradish, keep for 12 months or until the expiration date in unopened jars in the pantry. An open mustard container can still keep for 12 months if you store it in the refrigerator, but it can spoil within one month if you keep it at room temperature. An open container of relish lasts six months refrigerated and should not be stored in the pantry.
