I've done something before. Much like you've built a stone wall before.
When you send me proof of you building a stone wall, I'll send you proof of me doing something.
But you are too smart to 'dox' yourself by showing that easily-identifiable and world famous wall that you totally definitely did build, so I guess we are at stale mate.
I'd like to say this has been fun, but you have been so predictable and boring with your replies that would just be another lie.
