It kind of depends on how old the daughter is. If she's a teenager and she agreed, then they're both at fault because they both should have known something could go wrong. If it's a little girl, then the father is at fault because it's his job to protect her, whether or not she agreed to the mythbusting action. I wanted to go round in the washing machine when it was on when was I was little, but that wouldn't make it okay for my dad to let me. Yes, life is risky, but throwing something at your daughter's face is a risk that could easily be avoided.

It doesn't say anywhere in the post that he purposely was aiming for her... Also asking to go around in a washing machine is completely different , I'm sure the little girl didn't say ..'throw the card at my face daddy'.

If it would've been with something other than cards, I doubt that he would've done it

You never know a few years back i read an article of a dad who gave his daughter a cookie to feed a black bear that they ran into hiking when the girl turned around the bear pawed at her back for more luckily for her she had a backpack on and that the bear wasnt trying to intentionally hurt her it just wanted more cookies she was about 5-7 yo so there are parents that stupid to put their own children into those dangerous situations

I am impressed he was able to throw it quick enough to cut skin.

My friends did something similar when we were younger. We were throwing gift cards in a similar fashion across a basement, only to have one get stuck - shallowly lodged perpendicularly - in my friend's nose. He was sitting across the room watching TV at the time, but we all found it hysterical. Glad everyone in your situation had a sense of humor about it, it'll become one of your favorite memories.

I do hope that this was just one mistake he learned from and he's not actually that stupid.
