I attended a birth recently and the momma screamed bloody murder and thrashed around and pushed out a gorgeous wee babe, just like in the movies (the ones I hate because births are always portrayed as horrid messy screamy messes...but there you have it. After the momma laughed (well, she laughed the next day when the whole thing was a bit fuzzy).
Really, the mom is beautiful her own self and we declared her a fierce goddess warrior with monster growls. Watch out.
After all that, I had to have a lie down. Damn, women are strong.
