Mother's Day in the Single Ward
When I was in the Singles Ward in Fort Worth (a geographical church attandance group where only single young adult Mormons attend), Mother's day traditionally had a unique event. The men in the Elders Quorum (Male-only study class) would bring the women in the Relief Society (Women-only study class) a rose, for the "mother they will someday become."
On the one hand, it was nice to get a flower, but on the other hand, it was a painful reminder that I was still alone, single and childless. Thank goodness I only had to endure a couple of those days.
