Perhaps you are a professor or public school teacher of instrumental music. If so, consider giving a theory lesson or just share some knowledge about music and how it has changed your life.
There is a soldier waiting. Can you take time to play guitar with him or her? Do you give lessons? Work in a music store? Know a guitar teacher or player?
