Left teens alone whilst I went to work.
Came home to find DS(19) covered in shaving foam where DD(17) had ambushed him in the bathroom and DD stuck in the wash basket where DS had placed her and stuck the lid down after her ambush. Both of them giggling like toddlers until they realised I was home and DS then tries frantically to un wedge the wash basket to let her out. It's now broken and the bathroom is covered in shaving foam.
It's hard to believe that DS hits his 20s in a few months.
