Family has inappropriate responses to school shootings?

If I was in your place, I would be pissed. Why not get really upset, tell at them, and say what you said here. Tell your dad "instead of you show I g concern for your kid like normal adults vwould, but no, you reply with these little buckshot fucking funny face emojis. What if you didn't hear from me and you get to the school and find out I was shot and killed. The only one shot and killed. And then in my phone would be these little Bull shit funny faces that You seem to think are cute. Well, i, in case you are concerned am almost to worried or scared to go to school for fear in coming home in a body bag. I hope you get a nice little kick out of shit while you might be planning for my funeral." Now I'm thinking from your conversation in post that you are female. A " Daddy's Girl" of sorts. Kay the guilt trip on him as thick as you can and keep it going. Make him feel like shit.
