Here's a fun way to play it- say "We've talked so many times over the years, and I bet you don't even know my name."

If he does, explain that you said that because you don't know his, laugh about it. Get his name and put it in your phone if you think you'll forget.

If he doesn't, then say "Well we're in the same boat because I don't know yours!" Exchange names, and put it in your phone if you think you'll forget.
