Sarah has purchased a 100 liter packing of fertilizer to the live fence inside her garden although she was able to put it down to the cart, lifting it into the auto trunk will be a completely different degree of difficulty. She handles to drop it to the floor but when she squats down and tries to lift it her bladder muscles fail and she releases a spurt of urine! OK, mishaps happen. Not a huge deal, lets calm down and try again. What, she did it again? Lifting heavy objects is clearly not acceptable for girls with weak bladders!
