i truly don't know

i dont know where to start with this at all. i can't get the image of my dad hitting my mom in that small hotel room and just wondering how nobody heard all the noise and came to help. i know he didn't mean it but seriously dude?? this isn't the first time either but its just the first time i've SEEN him do it instead of hearing it. it doesn't happen often but gosh it is so scary.
