A funny story
While I'm sleeping, someone often helps doing dishes, cooking and laundry etc. at my place.
So I asked my husband if he did all the things.
He told me it's a "Kabouter".
I was surprised, because I thought we are the only people who are living in our appartment room.
Another day, I found my husband was doing dishes.
I said "Thank you" to him. But he insisted it's a "Kabouter".
TL;DR
My husband is a Kabouter.
