Thx for that.

A shark in a rock pool can operate as a loose cannon! And said loose cannon might well have the services of a lackey who tries to glean personal information from you, as a pretend friend, to pass on to his master for use against you. Such a lackey will tell you hurtful things and big lies about his master to try to befriend you. That lackey, who essentially can be said to run with the hare and hunt with the hounds, is very dishonest. His master, the shark, is also a rotter.
