Even though I was the only one still clinging to the pool ladder at the end of the course, the fact remains that the free lessons were available to anyone who wanted them.
Additionally, people who can't swim and have a fear of water generally avoid it.
Seems simple enough to me.
Of course, this constitutes incomplete assimilation into the hive and there's the rub.
I have no fear of water and I still ain't gettin into no hive :P
