Going on an LDS Mission

I just found this infographic, and it's making me cry.  Alec is getting ready to serve a mission for the Church of Jesus Christ of Latter-day Saints.  He's so excited to go, and so am I.  He'll make a great missionary - he knows so much, and likes helping people.  Only one more little thing to iron out, and his application for service will be turned in.  Why am I crying?
