Similar thing happened to me i was at a family wedding with over 100 people, I was with other kids inside the house playing and my mother saw that, and she was also helping with serving etc, I followed these older kids and they took me outside with them, we played near a pool that was covered and they started jumping on top i observed then doing it & they left , so I was alone and I did the same , jumped around a few times till one side of the cover was not securely attached & I fell in but luckly I was close to the edge of the pool not in the middle , and gripped my hands on the corner & held my body uptight pushing myself to get out and used my right leg too, the water was so deep it was up to my neck, I was there for a good 5 minutes I was close to letting go, and it began raining my mother was quick and wondered where I was, she opened the outside door pecking if I was possibly out in the backyard she saw me and quickly ran to get me

alhamdulilah.
The house was pretty big , it was like a mansion, if my mother did not think fast I would probably be not here today.
