Ask about your own sacraments. Ask about your parent or caregivers' sacraments. Who was there? Where did the sacraments happen? When did the sacraments happen? What was the experience like? Send an email to designated person that tells about your own sacraments.
Find out who are your godparents. Write a letter to them thanking them for being your godparent and add whatever else you'd like to say. Now mail the letter.
