This is what comes of doing good!

I haven't given blood for a long time. Not because I am against it in any way, it's just that when you get a tattoo, you're not allowed to give blood for a year following it. My year after my last tattoo ended a few months ago, and I've not had the opportunity to give until today. I only have one good vein, on my left arm. I've never had a vein visible in my right arm. So today, I get there, and answer the questionnaire, (which, by the way, I find so funny to answer) and then I get all set up. They sectioned off the arm, drew lines on me, and put some of that iodide stuff. I was totally ready.
She puts the needle in me, and it seems ok, but after a few seconds, she kind of frowns at my arm, and calls over this other guy to "take a look at this". I perk my ears up, because nobody likes to hear that. So then he does some stuff, asks how it feels, then says things should be ok. I'm sitting there for a bit, doing the squeeze-every-5-seconds thing, and then the girl comes back over. She looks for a few seconds at my arm, then calls another girl over to take a look. Well, by now, I'm thinking this is a huge mistake. She then informs me that I've clotted too early, so I've stopped giving the blood, or something. They fiddled with the needle for a minute or so, which hurt the whole time! They take it out, and I don't know what they're talking about, because I kept bleeding a lot. They had to change my gauze and everything. They wrapped my arm, and I left, with a juice box (that of course I spilled on my white clothing) and a Fig Newton.
As the day went on, my arm just hurt the whole time. Near the end of the day, after I take off the tape, I see my arm and see this delicious bruise:

I don't even know if you can really tell from the picture, but yeah, it's quite bruised. Not only is there that purple-ish part that's totally visible, surrounding it is also a deep purple bruise. I can't believe all this happened, from me just wanting to do a good deed. Well, never again, I tell you. Never again.
