Things that disappeared from my bathroom cabinet

When I was a student, I used to rent a small room in a flat near the university. I shared the flat with another student who was a guy slightly younger than me. At first, we got on really well. We talked a lot about our studies and other things and he could cook better than me (I"m really lousy) so he agreed to prepare the dinner sometimes. We also shared a bathroom cabinet. When I think about it almost makes me laugh. There were two separate shelves inside the cabinet but he often seemed to confuse them. Anyway, one day I noticed that my shampoo had been disappearing, little by little. I thought it was me who was using it up so quickly; I just had to control myself. But then I noticed that a packet of tissues had disappeared from my half of the cabinet and then I also lost a few razors. Well, that was enough. I asked my flatmate what it was all about. He denied having taken anything from my shelf! I got a bit angry and we stopped talking to each other. I took all my stuff except my toothbrush from the bathroom cabinet and put them in a drawer in my bedroom. After a week or two, the guy moved out from the flat. He found himself a bedsitter somewhere further away from the centre. A nice girl has just moved into the room next to mine. So far, we"ve got on really well with each other.
