Remember, you will hear all sorts of opinions on the internet. Before I had access, I was less aware of what other people think. Sometimes I wish I could undo knowing now. Sigh. Anyway, don’t let her trouble you. Lent is not silly. I think the whole liturgical year is a good idea. It is designed to help us move more deeply into the life of Christ each year. We follow the path of his birth, ministry, passion, resurrection, appearances, etc. Lent is the time we are remembering his time of preparation in the desert as we prepare again for Easter. It is especially a time to repent and be converted even more to Christ. It is good to do this every day of the year, of course, but we have a time built in each year for this, a whole season to think upon it. There is nothing of “patting ourselves on the back” in our trying to conform our lives to Christ.
Her accusation could only hold weight for an individual person, like a person who goes around proclaiming to anyone who will listen, “Look at me, all this praying I’m doing. I’m so wonderful. Etc.” Then what she is thinking about is the gospel passages about not letting your right hand know what your left is doing and about those who like to pray in public so that everyone can notice how wonderful they are have already been paid in full.
