My bad?

so i decided to wash my slippers - and this was the result. there was a lot of foam. luckily there is nothing wrong with the washing machine so there will be no irritated landlord.
night before the exam and im doing some last minute cramming. earlier on today i thought i had known quite a lot. and now im not quite so sure. wonderful. anyway this time tomorrow i will be one down - and then for some intense psychology revision!
