@ChecklistChikorita asks
I read an answer months ago and now it finally makes sense. Is that normal?
Jeff answers
Completely. Something like @SlabConfused's question about that little plastic jail becomes easier after you've handled a few holders and compared actual cards. I'd revisit the idea with a specific example in front of you. Learning doesn't always happen the first time a term passes through a conversation.
