another short story idea

Imagine a bed with two lovers way up high. they cannot see how far the fall would be beneath them and there is nothing at all to see around them or upwards, other than a dull light nothingness almost like the color of a cloud. they hang their arms and legs off the side and imagine what it would be like to fall. they jump on the bed and so can understand the concept of gravity and falling. they wonder what it would be like to jump and not land on the bed. they are born this way, in love and only knowing one another and their limited mattress life, thought they don’t see it as limited, because it is all they’ve ever known. until one morning, one lover wakes up to find that the other is not there. he wonders if she somehow ascended, but is almost certain that she has fallen. then he wonders whether it was intentional or by accident. his life changes completely now, without her. he only knew life with another. he only knew life in love. now he finds himself thinking to himself instead of sharing everything out loud. he has no outlet for the physical expression of his love. he begins a relationship with himself, because that is the only person there is left to have a relationship with, unless he were to make the intentional decision to jump off the bed. he even has a passing thought that he might find her if he were to do so.
