I think my dad and/or mom tried to teach me when I was little? And I never really got it? I'm not sure. I also went to swimming lessons once (my aunt took me..no idea why), and all I remember from it was being terrified because they held me under water. The only kind of swimming I can do is some kind of doggy paddling.
Trying to do the real swimming stroke, it seemed like all I did was just sank.
