Haha! Same here. But I know when it's manually engaged... Personally, I don't care... If it stayed on, that'd be a different story - as I'd get annoyed with it.
What year is your YJ? Your indicator switch (vacuum operated) could be bad or the lines running to it are messed up. Depending on your year it could be located on the axle where the vac. actuator is or on the firewall between the engine and the battery...
(Both of you should get on a computer and update your "Garage" in your profile so it makes it easier for people to help you out... YJ's changed a bit over the years of production ini addition to different engines having some mildly different components and functioning differently - as differently as an engine can function, that is)
