It's a bit unique to see someone immediately put their hands in their pockets ("No siree, Bob! You're not putting a ring on this finger!"). It doesn't necessarily mean that they want to refuse the proposal though. Rather, it likely speaks to the enormity of the moment ("Am I fully aware of what's happening right now? Am I ready? Am I worthy of this person?", etc) It's a BIG step! Congratulations, and thank you for adding captions! It definitely aids your deaf and hard of hearing viewers.
