Was very frustrated when I got home from work

I wish my housemate would leave. why is he hoovering so much? it is so annoying. in all honesty he is a nice lad but his habits frustrate me and he has HIV and didn't tell me before moving in. I think that this was dishonest and selfish of him as it made me very very worried when I discovered it. Because in theory he can easily spread HIV to me, borrowing my razor or toothbrush I left it in the shared bathroom which is only natural to do with a housemate who doesn't have a life shortening contagious disease.
