Your conversational partner is not a podcast.
Them being along for the ride is the main part of socializing ideas with them.
Be willing for the conversation to move a notch slower than the fastest you could comprehend, if it means the other person stays along for the ride.
The cadence of a conversation needs to be set by the carrying capacity of the slowest partner.
If you're a fast thinker and you're an expert in this domain, your clock speed will be an order of magnitude too fast for your conversational partner, overwhelming them and leaving them behind (and feeling bad and maybe even resentful).
You will be able to understand your own ideas an order of magnitude faster than others, because you already understand them!
