This morning my finger hurt because of the staples so when I wanted to close the jar I pressed with it from me. But because I put the staples there that were not in use it ended up stabbing my finger and it was quite deep. In order to avoid titanus, so I squeezed and spit out as much blood as possible, and this much blood came out, quite painful. But now it's getting better because I'm already bleeding, if I don't bleed it will be quite painful and will even swell later.
