Don't worry, they're not boring, humorless people. Before converting, you'll want to check into the missionaries available in your area. The missionaries will then come to your home and teach you lessons of the gospel that the Mormon Church is based upon. If at anytime you decide Mormonism isn't for you, simply tell the missionaries. If anything sounds strange to you, verify it through the ward's bishop.
Missionaries like to answer questions, so never be afraid to ask.
Mormons are focused on family. It's that simple. Women are considered the moral backbone of the family and are expected to care for the children. No small feat since many Mormon families form their own baseball teams. Now before the feminists readers get ticked off, the Church makes it clear that a husband and wife are equal partners.
