Ok so here's the deal. You replied to a guy who said "I don't know how ot is in the US. but..." with a dumb comment about how this is clearly a US card so it's a US issue. Your response made no sense (to me) because the original comment wasn't claiming anything that required US insight. They were simply providing input from their neck of the world.

Thus my confused response as to what this being a US social security card has to do with anything. Nobody asked for clarification on that, just used it as a launch point for their comment.
