L, one thing I forgot to mention, I was Initiated in 1966 and amd still very involved in my Fraternity.
As you can see, there are still many Alums who are a little long in the tooth that are still very involved and many others who want and have become members through Alum Procedures!
Point this out to your parents. If they have any questions, I am sure that any of us would be happy to talk with them!!!!!!!
