you’re not a coward okay you’re just looking out for yourself !! having a flight response in that situation is totally normal !!! you can try finding other ways to help or maybe help in a more passive way if that helps??
hey it’s ok man people at school are jerks!! if you feel like you can step in and stand up for this girl then go ahead but don’t bite off more than you can chew (cause i do that a lot and i just end up embarrassing myself haha)
