Should light switches be turned off every time you leave the room?

You'd be surprised by just how much power people could save by turning off the lights! On average, one light bulb uses sixty watts of energy per hour. Let's say you turn off a certain light for one hour daily. After a year, you'll end up saving over 22,000 watts of energy. Electricity is saved if lights are turned off every time you leave a room for more than a few minute, but the surge of power required to restart the light when it is switched back on may cancel any saving if the light has been turned off for only a few seconds.

Is it possible to control a light switch with remote control?
Yes. the two switches are called '3-way' switches. You will have to turn the fan/light on with one of the switches and leave BOTH switches in that position. The remote control unit will have to be wired in between the switch that is supplying power to the devices and the devices. This is the simplest way. You could also disable one of the switches and replace the remaining switch with the RC unit. If you are not sure how to deal with 3-way switches, learn about them first, or call a good electrician to do all of the work. Remeber that the black wire is hot, but only if the house was wired properly in the first place.
Can you connect one single light switch to another single light switch to control the same light on or off.?
Yes you can. There are three ways of doing this. Two are incorrect and one is the correct way of doing it.The two switches can be paralleled together to make the light fixture respond. Both of the two switches will always have to be in the on position. Either switch will turn the light off but the second switch will not turn the light on. Very inconvenient when you enter a room through one door and leave by another.The two switches can be wired in series. Both switches have to be on to operate the light but again if one of either switch is left in the off position the other switch will not operate the light fixture. Very inconvenient when you enter a room through one door and leave by another.The correct way of wiring two switches to control a central light fixture is with a three way switching system (two way in the UK). The two positions have to have special three way switches in each position. These types of switches sort out the problems of leaving a switch in a certain position to operate properly. The only criteria is that there be a three conductor cable joining the two three way switch boxes together.See related links below.
What is difference between single pole and double pole switch?
A single pole switch interrupts only one wire, which must be the live wire. A double pole switch interrupts both the live and the neutral, so it contains two separate switches operated by the same lever. Current practice is to use single-pole switches, to avoid a fault condition which could leave equipment live while switched off.

That depends on how he made you cry. If you leave every relationship just because they made you cry you'll end up alone forever. If he did it on an accident then you should forgive him. But if it something huge then dump him as quickly as you can.
How do you get all of the light switches to be in the down position for off when you have more than one switch for them?
Three way switches do not have a up-on down-off position. With the lights off, reposition the switches so that the handles are all down. This is the start position and depending on how you enter the room and turn on the lights certain switches will be left up when you leave the room. That is just the design of the switches and for the asthetics of the look, all handles down the lights will be out.
