Ive never taken a physics class..
but if I had, I probably would have failed.
Newton's Law of Gravity:
If child A is sitting in the stroller,
and child B is sitting on the handles of the stroller,
if Child A is removed,
Child B will fall from lack of gravitational weight pull that child A provided.
Child B will do a face plant on the concrete and end up with a fat, bloody lip, chin and elbow.
Mommy of A & B needs to go back and take a physics class
cause she SUCKS!
