Little bit irresponsible to leave the door open...
I know my parents have love. I've never heard nor seen them (thankfully) but I know they do.
They probably wouldn't be as happy as they are if they didn't.
But my parents would most certainly make sure that their door is closed before they have love.
They wouldn't want to walk in on me if I was having love, and I don't want to walk in on them if they're having love.
Some people have weird parents.
