I was in kitchen and cutting some vegetables with knife which I just sharpened . I think I was cutting so close to my fingers, and doing multi task, the knife cut my finger. The blood was gushing out, I tried to stop with  water. Then I went to my medicine cabinet, and grabbed a box of band aid. The cut was big, so I was looking for long and wide one, which cover my cut. I found one which has some antiseptic cream on.  I cleaned my wound, and pressed cotton on wound for a while till the blood stopped. Finally when it stopped then I peeled the paper from the band aid, and it exposed the sticky part of band aid. I immediately put the sticky part on my skin adjusting it according to my wound, so cushiony antiseptic part directly falls on my wound and covers it nicely. Then I pressed both side so it sticks to my finger well and wrapped around my finger securely.
How did they hurt themselves ?
