I just came in the communal front door of my apartment block behind my neighbour who is a paramedic. He was wearing his uniform and had obviously just come in from work. I came in had a bath and then about 10 mins after coming out the bath I noticed I had a large cut at the bottom of the palm of my hand, it was obviously new because it was bleeding. What are the chances that I either cut myself while I was out (went from my house to my mum's and back again) and caught something or possibly I had the cut when I came in behind my neighbour and he could have had a trace of blood on his paramedics uniform and I touched where he did and got some blood in my cut. After my bath I was puttiing my clean underwear away in the drawer and now I am worried that I have got some blood on my clean clothing. I am now going mad with worry because I don't know where I got this cut and what I have been touching with it
