MIL is staying with us. Every night she had a bath - fine. Normal, in fact. Every time I go into the bathroom after she's had a bath, there is masses and masses of foam in the sink and the toilet. Like she has run a bath with loads and loads of bubbles, then scooped a couple of bucket loads of foam out and put it in the sink and toilet. Bizarrely, there is no trace of bubbles in the bath and our bubble bath goes down at a reasonable rate.
What is she doing?! I am aware this is not exactly much of a problem in the grand scheme of things, but it happens every time she stays and I really really want to know the answer (although not, of course, enough to ask her). Please tell me you do this and there is a perfectly reasonably explanation.
