This is no time to stop thinking of Works of Mercy. You don't have the usual opportunities for doing things outside your home / neighborhood, but that doesn't mean that you have no chances to act mercifully.
Remember that the Works of Mercy continue until you meet the Lord and give an accounting of your life. While our lives are a bit limited, we still have the opportunity to reach out in service to each other.
You can find ideas on these lists for things to do in your everyday life.
