Swimming in the sea is simply an unsafe proposition. There are too many unknown variables and factors beyond our control, making it not worth the risk for someone like me who is risk-averse. I’m not talking about an irrational phobia; I just believe that bad things can happen in an instant, and you can’t go up against nature when tragedy strikes.

Why do I bring this up? The first episode of Bad Sisters shows that the girls have an annual tradition of swimming in the cold sea on Christmas. It looked dangerous.
