My dad was in this sucky war...

Hey, Thanks for taking the time to read this. I'm only 13 years old. My dad was in this war. He's still really affected by it. He got emotional in the war seens in forest Gump. Whenever I start to wacth a Vietnam movie my dad acts weird & turns it off or leaves. I don't really no much about this war but it seems like it was a senseless thing. Thanks for reading this. Live long and prosper!
