I don't get it...

How pathetic can someone get?

I know a girl who fell pregnant at a young age - I know that's not bad.
Her child is about 3 or 4 now, and she STILL lives with her parents... - still not really bad.
Her partner even lives there too (good for them I guess)...

Now for the pathetic part -

Why on Earth would you PLAN a SECOND child, if you couldn't even afford to live as an adult in your own home with the first one?

Someone Please explain??
