Omg that's so irresponsible of your colleague! Lucky u have 贵人to help u. When I was a child, I almost drowned in the pool before also, that's why up till now I don't know how to swim, cos I got phobia of putting my face underwater. I remember in sec school we HAVE to pass a swimming test, I tried my best to bluff the GP that I'm allergic to chlorine so I can be excused, but the GP was too clever, so I bo bian, LL, has to take the lessons, but I always hide in the back n only participated half the time. Then when it came time for the test, we had to swim abt 1/2 the width of the pool, I remember taking a super super deep breath, n just jumping as far as my skinny chicken legs would take me into the pool, n that literally covered 1/2 the distance required already, then I literally floated down the other half. I didn't move my face, my hands or my legs, I floated, like a crocodile... or a dead log. I could even hear my classmates asking each other eh what stroke is she using har?? Haha, who cares, I floated my way to the finishing line, n I passed! Hehehe.
