This kid at my school poked me with a sowing needle just to get a laugh. It didn't go in that far (just a small poke) like a tetnis shot and I don't know where it's been. The needle is like 1 inch long or less and like 1 15th of it went in in probably. There was no blood on the needle either. Am I at risk? It didn't go deep at all and it lasted less than a second
