Your dad sounds like an asshole and id avoid bringing up running. I’d enjoy talking about it. But I wouldn’t want a teaching lesson from someone who has, as far as I know, no credentials or authority on the topic because, if we assume it’s like the post, none were given. Plus I’d rather they find out my level of knowledge before they assume I know nothing. Basic respect. Your dad has none. And you don’t either.

Edit: most running plans aren’t gendered so he may not even know it’s from a woman. Many plans get shared, gasp, through social media and credit can be lost. You’re actually fucking awful at drawing logical conclusions. Take a college course in logic once you reach there as I can’t imagine you’re that old or experienced with your approach to communications.
