They are male member of the church who comes to the house to teach lessons about the gospel from our magazine. They are assigned in pairs to each adult woman in the church. They are also responsible along with a team of women (our visiting teachers) to make sure that basic necessities are available to every family. The Latter Day Saints are very aware it's hard to set our sites on higher spiritual ground when tummy's are empty.
Some of the things home teachers have done for me since I've been in the church along with teaching wonderful lessons are: Comming to the meetings when I had to move to make sure I had the information correct, driving the moving truck out to my new place, helping with the heavy yard work that I couldn't do, rescuing me when I tried to add a hose to my kitchen faucet and couldn't finish the project.
