I once took Brain & Kathleen on a bus trip to the Worchester Science Museum, along with my son, Raymond.  The boys were probably about 6 and Kathleen a couple years younger.  I over-heard Kathleen ask her brother "Brian, What's a museum?"  Brian's answer confused Kathleen even more when he told her, "it's a place where they have stuff under glass".  The look on Kathleen's face was priceless.  Brain was always Kathleen's Big Brother.  Brian will be greatly missed.  He was a great person.  My heart goes out to you for your great loss.  May God comfort you.
