<human>:  How to mow a lawn efficiently?
<bot>: To mow a lawn efficiently, start by making sure that the mower blades are sharp. This will ensure a clean cut, which will make the lawn look neat and well groomed. Make sure the grass isn't too long before you begin; if it is, use a trimmer to cut it down to the appropriate height before starting the mower. Move across the lawn in rows, making sure to overlap slightly to ensure that the entire area is mowed. When you reach the edges of the lawn, turn the mower at a sharp angle to get the grass in the corners. Finally, before going inside, double check the entire lawn to make sure you did not miss any patches of grass.
