lesson #4 toilet lid down

One thing that most people should really do is put the toilet lid down after they are done using it. Firstly when you flush, a cloud of bacteria is released into the air and can take up to an hour before settling down, and when it does, it is all over the bathroom. Putting the lid down before you flush is a great way to combat this. Second, if you own a pet, it is very important to keep it down so your animals don't play or drink out of the water. This water could cause your pets to get the bacteria on or in them and could make them very sick. Lastly, it is annoying when you go into the bathroom when it is dark and sit down, only to fall in! It is not a fun experience and nobody should be subject to that. By having the lid down, this is prevented.
