When I was about 11 years old me and my two(not so bright)sisters were at a hotel swimming pool.I was sitting by the pool watching my one sister(we will call her K) that could barely swim herself teach my other sister who was terrified of water(we will call her B) how to swim.They started out in shallow end swimming underwater when B went off course and ended up in the deep end.When she came up she started panicing and K went over to help her. B grabed on to K pushing her under water and then K paniced and pushed B under trying to stay above water.They did this cute little routine for a while (Up pops K down goes K Up pops B down goes B)If it was'nt so life threatening It would of been hilarious.(I did start laughing...at first)Then it got to the point where i knew i had to do something because they were getting ready to drown...they were swallowing tons of water and there was no time to get help. There where no floation devices anywhere!!!So I sat on the little latter and stuck both my legs out as far as they would go and told them to grab a leg, they did.They layed next to the pool for about 30 minutes spitting out water and crying.We never told mom.
