A lot of people don't like mission stories. Members have heard too many already and non-members don't really understand them. This is frustrating to returned missionaries because all our best stories are from the mission. Also, not a day goes by that something doesn't remind you of something that happened on the mission.
My wife Maude is long-suffering. She'll never say anything but I can actually see her eyes glaze over as soon as I utter the words, "this one time, in Argentina..." She probably has a pretty skewed view of Mormons, since most of stories she's heard about them are terrible.
Mission stories generally fall into three categories.
1) Stupid things that missionaries do. I'd wager this is probably the largest category (you can draw your own conclusions as to why).
2) Crazy/weird people encountered in the mission field.
3) Spiritual experiences. This is probably the smallest group.
Well, I am here to provide a safe haven for all your pent-up tales. I love mission stories. Even those in category 3. Maybe because I am "less active" (happy, Steve FSF?) I haven't heard very many. Maybe this will count as your virtual Home Teaching visit.
