Most of us cannot imagine what it is like to be home-bound and totally dependent on others. Many will response with love and joy when we reach out to them. Send a greeting to a home-bound parishioner.
Your parish office can provide you with some names of people in your area who might appreciate a friendly greeting. Local nursing homes are also appreciative of letters and cards which are sent to their residents.
Who knows, you might develop a relationship with someone who can offer you the insights which only come with time.
