What does between Scylla and Charybdis mean?
When working on a project of two or more conflicting elements and your hands are full so you can't do anything reffering to the greek story of the Oddesy.
Odysseus chooses to pass by Scylla because, Scylla will only kill 6 men, one for each head. Charybdis will sink the ship, killing everyone. Circe has also advised Odysseus to do choose Scylla. Further, Charybdis is a visible danger, and Odysseus uses Charybdis to encourage his men to pass by quickly. Finally, passing by Scylla and Charybdis is given as the only way for Odysseus to get home from where he is.
