I have no idea why you would decide to avoid Mass on Ash Wednesday, unless it is a serous inconvenience. Perhaps you could explain why you personally choose to avoid it? It might be helpful to others reading these posts.
I have often found, in working with people, that those who thin others are looking at them are people who have an unresolved issue, and presume others can see it. They can’t; unless you bring it up.
And the same question applies to Good Friday; if you say you are a Catholic, then the Triduum - Holy Thursday Mass recalling the Last Supper; Good Friday recollection of Christ’s torture, execution and death, and Holy Saturday Night, the highest feast day of the Church appears to be something for which you have little appreciation.
And by the way, Good Friday is not a Mass. But it baffles me why, considering the absolute intimacy to the liturgical calendar and to what we do at Mass, that you would avoid it. Perhaps you could give some more details?
