In the first act, a letter arrives for Grandpa.
Robbie: The return name and address is Pete Waters. RFD. Number 1, Chesterton.
Pete Waters is an old friend of Grandpa's.
Grandpa: He was my roommate in college.
In the letter, Peter invites Grandpa to a reunion, a time to see their old friends again.
Grandpa: He is writing to invite me to spend a weekend with him at his farm. He's planning a get-together with two or three other college friends. Kind of fifty-year anniversary reunion.
Will Grandpa go to the reunion?
