I have a friend who is living quite close to me. He recently moved into a house with others from his course. Originally I'm sure he said that he was living with one girl and two boys, more than once. I remember going around and I'm sure he said something like the girl isn't in today, but I met the two boys. Then today we were on a walk together and he told me about the boys he was living with, how they were etc. Then I asked 'how is the girl?', and he said what girl? I told him I'm sure you said you were living with a girl and he said that there are only 3 rooms. I have no idea why he lied about this, any ideas?
