I have a cactus sitting in my kitchen window (so technically, this could have happened anywhere) and I reached for a paper towel. In the process I knocked the cactus off the window onto my hand.
It didn't hurt, but there were A LOT of little blonde thorns in my two fingers. I got most of them with tweezers, but now I can't see the ones that are left. I can only feel them when my fingers brush up against something. Now, that does hurt. But, as you can see it hasn't stopped me from blogging!
It will be weeks before I get them all out.
