Today's prompt is: Leash
First thought, of course, is the tether thats used for leading something such as a dog. Or perhaps a child. I know that many look askance at a parent with a child on a leash, but let me tell you that if you have ever had a young one whose middle name is bullet you know the peace of mind that even though they have some freedom to roam, you still know where they are. Even as they get older it is hard to release the leash that binds them to you, but it necessary.
In hunting country leash sometimes refers to a set of three, like three foxes or deer.
Leach also infers control, such as having a leach on your temper.
