At Lourdes, the Virgin Mary appeared to Bernadette Soubirous eighteen times in 1858. The apparitions began at the start of Lent. A number of times over the many weeks, when Bernadette asked a question or presented the priest's demands, the Mother of God simply smiled. Heaven smiling on us: not grumbling, not frowning, not tysk-ing, not eye rolling - just smiling.
When I was a young priest I had a gentlemanly pastor who smiled a lot. He smiled at his detractors (every priest has them) and at those who didn't wish him well. I don't know if his smiles were genuine, but if they were forced, then AA would say, "Fake it till you make it." That alone is commendable.
What a neat idea for Lent: to learn from heaven and smile more. Maybe to consciously smile three times each day. At Lourdes, looking upon our complaining, our toxic arguing, our willful ignorance - heaven smiled. We might take the hint.
