Only a mother would...
stay up all night watching her feverish child
eat her child's unfinished food and not think it's gross
ignore the numbness in her thigh when her child uses it as a pillow
wipe up vomit lovingly from the floor
sacrifice her favourite part of the chicken for her child
cuddle her teething child closer when he suckles and bites
carry her tired child despite her bad back
skip lunch to save and buy her child a much-desired book
accept her child with open arms after he made a mistake that hurt
drive through hail to deliver a forgotten jacket to the classroom
give her life to her child
Only a mother would. More precisely, only a mother at heart would.
