Have you ever noticed when you start telling somebody something other things happen that make you "put your money where your mouth is"?  This happens a lot as a missionary.  We share the gospel then things come our way to test us and make sure we are truly sincere.  
Elder Miller and I have been sharing a message with people about getting through trials.  We use a talk from Elder Joseph B. Wirthlin in 2008 called "Come What May, and Love it."  Elder Wirthlin gives a few different things to do so we can get through trials.  I want to focus on the first one.  Learn to laugh.  Of course this isn't appropriate in all situations but it helps in some of the more embarrassing and frustrating ones.  Most peoples first reaction to adversity might be to get angry, or if they have better control to simply move on.  But when we learn to laugh we relieve the stress of situations and can pay attention to the bright side of things.  Here is what happened... 

Last week we were going to dinner and had a little bit of a fender bender.  It was pretty stressful but we didn't have too much time to think about it.  At the end of dinner we shared the message, Come What May, and Love it...    After we were talking and decided that we had better practice what we preached and laugh it off.  It helped ease the stress quite a bit but there was still a lot we had to deal with because of the situation.  We got over it and whats done is done right?  Apparently we didn't learn our lesson.  A few days later we went and shared this message with a different family.  We felt like it was a good visit and everything was going great.  It was a very cold 8 pm and we left the appointment to go to the library... and got a flat tire.  Because of our previous experience we knew there wasn't any point in doing anything but laugh it off, fix it, and move on.  So we did and it all worked out.
I know these situations really don't matter much and that's the point.  Laughter made us realize how little they mattered.  So when things don't quite go our way, laugh it off and find the joy in the journey.
