I had the best conversation with you earlier this evening. It started by you telling me you have to ask me something serious, and telling me to sit down, look you in the eyes and pinky-promise to tell the truth no matter what.
You made me nervous. lol.
It ended with you knowing and understanding that the Tooth Fairy, Easter Bunny, and Santa Clause are not real.
Mermaids, however, are still a very realistic possibility.
