Often I find my self praying the Angelus or the rosary etc., on my own. Take the Angelus’ conclusion for example:
Let us pray: Pour forth, we beseech thee, O Lord, Your grace into our hearts, that we to whom the incarnation of Christ Thy Son was made known by the message of an angel, may by His Passion and Cross be brought to the glory of His resurrection; through the same Christ our Lord. Amen.
Should the oremus be dropped in solo-recitation?
