When my mother saved me.
So my mom was trying to teach me how to ride a bike.
There also was another kid on a bike.
......
And there was a dog running towards us.
So my mom lifts me up and the dog starts climbing on her to get me.
So after some time, the dog starts going after the other kid instead.
And it bite his head.
If my mother wouldn't save me, my head would have got bitten.
