I never served a mission (unless you consider Peace Corps a mission for the US Govt.) so I always try to support missionaries in whatever way possible. Usually that means feeding a gaggle of elders. (MoBob cooks.)
Overseas though it's different. I actually make an effort to go on splits with the sister missionaries - if I can find them. Most recently I accompanied them in Lyon. It's fun, and gives me a glimpse of missionary life that I wouldn't have otherwise. Shortly after I joined the Church President Hinckley gave a talk which many interpreted to mean that young women shouldn't go on missions. So the generation of sister missionaries I now see are the extra-dedicated.
I already knew that I had limited time in Brussels so I didn't make an effort to seek out the sister missionaries. Surprisingly I ran across two companionships. I decided to take a walk through Jubilee Park and saw two young ladies with name tags sitting with two other young women. It turns out that Sr. B (from Salt Lake City) and Sr. S (from São Paulo) were duking it out with two Jehovah's Witnesses. They were happy to let me join them so that at least the JWs were outnumbered. I could feel the sisters' frustrations because the JWs were so Biblically literate - plus they were native French speakers. At the end the JWs graciously admitted that next time they will discuss the scriptures in English. Afterwards we walked through the park and I bought them waffles. It was a little disconcerting to think that I'm old enough to have a child their age. (Well, if I were a teen mother.)
Yesterday on the way from the office to the metro I came across the other pair of sister missionaries. Like the others, they were so...perky. Was I that enthusiastic at that age? (At that age I was drinking beer at the Workies' in Canberra.) They said the work was going "super great!" Good for them. I understand how challenging missionary work is in Europe, and I'm sure the increasing number of immigrant converts will change the face of the Church in Europe.
(MB once asked me why I dress like the sister missionaries. We certainly all have the same sensible shoes.)
I haven't seen sister missionaries in quite a while...maybe three years? We don't have them in this ward, of course there are no missionaries in main land China, and we didn't have them before that in our Tucson ward either.
However, just last week when I was at the temple, there were several sister missionaries there...maybe 6? It was so neat to see how enthusiastic they were, reverent yet exuding cheerfulness and almost a bubbliness.
When I was 20 I was a ward missionary and went on splits with the sister missionaries every week. It was an amazing growing experience for me.
As a missionary in Austria, the Jay-Dubs were the utter bane of our existence. In fact, it wouldn't be a lie to say, I grew to hate them with a capital H. My advice to missionaries: don't even engage them. They're not worth the time. At all. (Bet that little opinion of mine left you taken aback, eh?)
