Sometimes I wonder, why bother?

Look at this post on Reddit. Watch the video. Read my comment and then read the OPs response. I'm far from an expert but I do know PLAY on a high level. It's like the whole post went over the OPs head. Why post the video if you're not open to critique? I'm ALWAYS open to criticism.

I'm a reddit refugee

You made valid points on the post. I think the OP just wanted to show off some improvements with their dog, not everyone is set on a growth mindset.

Thankfully I'm not on reddit much these days
