My mother has lost a hearing aid. This happens a lot. Only usually we find them again pretty quickly. This time she says she put it on her bedside table and it dropped off. Shouldn't be difficult to locate, should it? OK, things often bounce further than seems feasible, but there's still only a relatively small area of floor-space to search. Well I've been down on my stomach, I've moved furniture, I've done everything bar take the carpet up and there's no sign of it.
