This is your psychological problem, maybe you have a bit of cleanliness and obsessive-compulsive card, don't be too deliberate to remember something

I wash it thoroughly and am available without worrying about it. If you care about it, don't use it, just throw it away.

They should still be alive, they can all be mixed up in the sewers.
