Lynn sat on the bench and opened her bag. She took out an old crust of bread and broke it into small bits. She tossed them out in a haphazard pattern at first. Then, as birds congregated she sowed her crumbs in a way that kept the bigger birds back from where the smaller ones came to feed. She gave me a hunk of bread and frowned disapprovingly as I tossed a large piece halfway between two monster blackbirds.
