What does Fr. Leahy do on his birthday? How ab Valentine’s Day?

I don’t know. It’s on July 16. He’ll be 72 this year. I’m sure if you send him a card, one of the things he’ll do is read it. Valentine’s Day is not currently recognized other than in some local traditions in the Roman Catholic Church, so it’s quite likely Father Leahy does nothing special to observe St. Valentine on February 14.

I guess we need his address to send him a card, right? Is the address listed on the university contact his real address?

Yes, he will receive mail sent to that address.
