Input: Text: in all honesty this happened years ago when me and my sister were just kids but a good laugh nevertheless

so my three year old sister was happily rolling around the house on one her little ride on cars (something like [this](http://www.obantoycupboard.org/wp-content/uploads/catablog/originals/ac528%20toddler%20ride%20on%20car%201.jpg)). pushing herself along by her tiny feet only gets her so far so she looks up at me and yells out "push, push!". being the older brother i am, i get down on my knees and hold the bottom of her ride

i slowly roll it to and fro and ask her if she's ready, getting her all hyped. and then i pushed.

except i severely miscalculated the force. instead of her gliding across the floor the car zipped forward and swerved, sending my sister flying across the floor, slicing her chin against one of our floor vents.

she began crying and my parents rushed in. next thing you know dad's racing all of us to the nearest hospital with my mum holding a handkerchief to my sister now split chin

TIFU by giving my sister a small 'push'
