That was a product of my mothers ability to have kids, apparently she had two miscarriages before I came.

And I guess she knew the whole situation, she's the only that explained it all to me before my pops came home from work.

Weirdly enough, I visited my aunt (his sister) in another country about 8 years ago, she made mention of seeing one of his kids ( who would have been 40+) on the bus all the time.
