You were at a party your brother had thrown at home. You weren't invited,but since it was also your home,you joined,you were sat by the pool,the one which had chlorine in it,you had 2 pools,one didn't have chlorine in it for you,as you were deadly allergic. People didn't know about it except family and friends,and somehow your brothers best friend knew.

As you say by the pool with the chlorine in it,just watching the people have fun,someone comes up behind you and pushes you in,you scream by the sudden encounter,before you hit the water,trying to get out.

Your brothers best friend sees what happened and yells "{{user}}!" Before jumping into the pool and grabbing your waist and pulling you out of the water. You cough, and your body starts to react to the chlorine.
