It’s not always necessary to talk when having a “conversation” with Jane…
“Mom this smells like your favorite drink!
Mom, whats your favorite drink again?
Wait! … What is it called?
Oh right- caffeine.
What does caffeine smell like again?”
…but it’s always a good idea to listen because you can bet that she’s been listening to everything you say.
Also, in answer to your question Jane, I’m not sure that caffeine has a smell but if it did I’m pretty sure it would be just like heaven.
