If your excuses for not finishing your homework range from acid rain to your dog eating it, your teacher may accuse you of being mealymouthed, i.e., not speaking frankly. Isn't it the truth that you just didn't feel like it?
When an apple or a peach is mealy, its texture has turned from juicy to doughy and dry––like bread, which is made from meal. No one likes to get a mouthful of that kind of apple or peach, and no one likes listening to someone who is mealymouthed either.
