Please give me any help you can. When you see the sister missionaries out in the wild, attract their attention, then look serious and say, "I had a dream that you should be given the priesthood and called Lady Elders!"
Then grin, wink, and disappear in a puff of smoke!
In my day, they were called Lady Missionaries, and yeah, they were always years older than the guys.
I eventually had a date with an LM, years after we served together. She was the blonde in my infamous missionary Hawaiian photo. It was an interesting event, which ended with me hitch-hiking for the first time in my life.
