Wow. You are very big on cleanliness and I admire that.
Recently, in my hostel. Our bathroom drainage had an issue. So we have no choice but to pack the water inside WC after bathing until we were able to secure a plumber. It was a very uncomfortable experience.
There is a lot illness that can be avoided by cleanliness, also a clean environment gives a clear mind.
The same experience I had living with my brother, very uncomfortable situation.
Thanks for reading, sis
