I just received a couple of pictures along with this message from another missionary mom who saw one of my posts in ldsmissionarymoms.

Gayleen is this your son? if so i met him at the mission home when his ward came to temple night. I think he was brand new and seemed very happy to be in Japan.
His comp Elder Everett is a great guy. My son, Joel Farb,the guy in the white shirt (It was the first day they could take off their jackets so he did!), was in his district before and they enjoyed going on splits a having a great time working together. They were in the same zone and met every week in his last area in Saijo. So as you are probably aware, your son got a really good trainer! You can tell by the smile on their faces, can't you!
