No problem friend, happy to help. I still think it's a stupid phrase, you don't have anyone else's experience and you're never not alive to experience anything. All it does is "I'm trying to make my point stronger by making you feel bad about questioning it because I'm going to reply that you can't question what I said"

I guess you could take the idea that someone has an experience that may be different to yours and that you aren't able to dictate as a personal affront rather than a plain fact, but I recommend against it. That doesn't seem interesting or productive, it seems like getting worked up over something beyond your control and of no consequence.
