How can I get my parents to see that social interaction and fun are irrational ? I have other things to do?

It is good you think critically and hell this proves you're gonna be ok. You know what you want and who you are, the majority of the population has no clue what they really want or who they are. You're still in high school so your parents are trying to get the last push to make you who they want you to be before you truly grow up. You just gotta tell em straight up and they won't like it at first - may be a rough couple days but in the long run it's so much better. I smoke a bit of bud every now and then and my parents are de-sensitized to it cause I brought it up and told them right off the bat, I've explained to them the benefits and told them it's not an addiction problem or any of that bullshit. I haven't moved on to other things because addiction and "gateway" is **** for weak minded people. So yeah now my parents make playful jokes about it, just tell yours what you just typed except maybe spare some details haha -- and in the end it'll be a better existance! Hope this helps!
