St Athanasius was where I attended my first TLM as well, as well as my first TLM High Mass and pre-1955 Holy Week (assuming Fr Ringrose was using the pre-1955 rites in the late 1980s, I honestly don't remember). I had previously attended Novus Ordo Latin Masses from time to time, and thought it would be the same, just more elaborated prayers. I didn't realize it would be almost entirely sotto voce and was quite bewildered by it all.
