My sons are now teenagers, the oldest is working and three of us like to shower in the morning and the youngest likes to do so in the evening. I am first up and out, oldest son goes in straight after me closely followed by the youngest to wash and do his teeth and my husband goes in after that. It works, we have the occasional shout of hurry up but mostly it is a good system.
But it is not just bathrooms though is it, we seem to be conditioned to believe we need more space when actually we probably spend most of our time in the same areas. Of course if you have a larger family then you will need more space than a childless couple but sometimes it is about storing stuff.
While out walking yesterday we saw this property for sale and it is also yesterdays picture of the day.
