Sure, but in this case it was a case of me not knowing one could check their Smile balance. GP posted their balance, prompting me to check mine, and the total was the same. That feels more akin to me going into a room and the first person I talk to having the same birthday as me than just finding 2 people in a room who happen to have the same birthday.
The situation is probably closer to this: Lots of people went into a room and asked someone what their birthday is. Only you happened to have the same one, so no one else said anything.
But, congrats on using up your luck for the next month or so. :)
