How can I tell someone else has used my toilet?

Generally, you can't tell that others have used your own toilet, as long as you write a seal on the toilet, then you can only use it yourself.

1. In the toilet where it is not easy to be noticed and must be touched, quietly set up a secret mark that is not easy to be discovered, so that you only need to check whether there is any change in the secret mark;

2. Install a hidden monitoring in a hidden place.

Look for any new toilet paper in the trash can and see if there are any hair strands left in the sink.

If you want to do that, you can make a mark on the toilet, the kind that disappears when you flush the water.

I think that others who have used your toilet will definitely leave certain traces, as long as you find it with your heart, you will definitely be able to find it.

Because someone else has used their own toilet, the contents of it must be the same as if you put it at home.

Personally, I think it's normal for someone else to use their own toilet, and if your friends come to your house, then you can't avoid it.
