You might have a senior that loves to read and they might share an appreciation of an author's work with a student. In Hanover we had a young man who likes history and he was matched up with a senior who has lived through several wars.

In Norwell, we had a student that was a Democrat and the senior was a Republican. They both agreed to disagree and they had some great conversations.

They both discovered they had once visited the same restaurant in Mexico when they were on their respective vacations.
