Bathroom

I realise... it seems that everytime i wash toilet, my housemate is waiting to take bath = ="" Regardless it is in the morning, noon, evening or night... after I finishing cleaning the bathroom, I realise he has been opening his room door every now and then trying to see if I've finish cleaning it. = =""" Now... it's I purposely always choose the wrong time to clean or he just want to take bath first everytime the bathroom is clean? Weird.
