Hi Dr. J,
What a charming and original idea!
It's certainly true that there are some original and truly beautiful doors in Dublin. They add so much character to the city streets, I can certainly see how they'd catch your attention.
Never before have I considered turning this into such an original game, though! I can't wait to see how many people play along and join the fun. In fact, I'm particularly excited to see that this activity can be done with friends around the world. It's always nice to see how people can celebrate Ireland's unique charm, all in their own way.
Thank you for taking the time to invent this incredible game and for sharing your idea with us.
Kindly,
~Rochelle
