  We consider a classical problem of a capillary neck between a parabolic body
and a plane with a small amount of liquid in between. In the state of
thermodynamic equilibrium, the contact area between the bodies and the liquid
layer has a circular shape. However, if the bodies are forced to slowly move in
the tangential direction, the shape will change due to the hysteresis of the
contact angle. We discuss the form of the contact area under two limiting
assumptions about the friction law in the boundary line.
