Actually they love to assemble jigsaw puzzles, but both of them have trouble concentrating and staying focused (doing homework with them f.ex. is extremely stressful, especially with my son). So I bought them a nice new puzzle with an African picture and I told them that when this puzzle was done, we would go to the swimming pool together.
It took them three days. So if you're looking for us on Monday, you can find us in the swimming pool!
