Having been warned that male sea lions were somewhat territorial, I moved as quickly as I could to steer my dad the other direction. By the time I reached him, the sea lion was no more than a few arm lengths away. Again, thankfully, it did not take much interest in us.

Their tameness was disarming and beautiful, but it also made them look a little stupid.
