at the Latin Mass we don't respond at all

Ditto in the Maronite Rite. Probably because in both rites, we only receive on the tongue.

We recieve in a Latin Novus Ordo Mass by intinction and thus must recieve on the tongue. The priest holds the Host up to our eye level, or down really, as we kneel on an Altar rail, and says the words Body of Christ and we answer with an Amen. When I went to the Indult Tridentine Mass I was warned not to say amen, but I forgot!! and said it anyway from habit.
