The iPod got me. Never had one. Never had a friend who did. This could be a Gen X experience or a cash-poor Millennial experience. If it hadn't been for the hint I would not have got past that part.

I also didn't have that particular Nokia so it took me a moment to figure out which button deleted mistakes. Mistakenly thinking that the CAPTCHA designers might not have implemented that part of the interface didn't help.

Had to guess on the boomerang. I've seen boomerangs but didn't know that's what they're called nor have I ever posted one. Again, this could be an "I don't post on that platform" or an "I only post pictures and haven't used that feature" experience. I definitely have an account on at least one platform that hosts them though.

I am technically not a Millennial. The term for my cohort is Xennial, I believe.
