Last October, the minimum age for missionaries of the Church of Jesus Christ of Latter Day Saints to volunteer was lowered from 21 to 19 for the women, and 19 to 18 for the men. This was a big change, and turned out to be perfect timing for my younger sister, who was just about to turn 19. She faithfully wrote me every week of my mission, and I must say they were the most entertaining letters I ever received. When the announcement was made, she felt a desire to serve. She was called to serve in the Scotland/ Ireland mission, and entered the MTC today. I am so proud of her.
This is a picture of her on her weekly "day off" where she can do some sightseeing:
