Swimming

What do you classify as a non-swimmer???? is it someone who can swim but not to the deep end or someone who can't swim at all?? well the lifeguards at my local swimming baths wouldn't let my brother swim further than the non swimmers line because he isn't a strong swimmer, how the hell am i meant to teach him to swim when we are told to go to the shallow end, he can stand up half way down the pool, its not like he is going to drown with his feet firmly planted on the bottom of the pool. what can i say he is tall for his age.

i paid £3.80 just so i can sit in the pool and watch my brothers play in the water when they want to swim lengths so we stuck with widths. its not like i can't help him if he does drown i do have a lifesavers award plus i have saved my siblings in the past when one has been silly in the past and couldn't swim properly. its stupid really stupid.
