If you prick me, do I not bleed?

Tonight for our FHE activity, we went to the local blood place and donated blood. I know, right? Weird for an activity, but hey, we're all adults, so I guess that's what we do! So we went, and I was in the beginning of the line, which was awesome. I've never been to the blood place, they've always just come to my work, so it was a new experience! They have a TV there, I didn't know this. We were watching Live Free or Die Hard, which is so awesome to watch. While people are dying and blood flowing out of their injuries on screen, you're having blood flow out of your arm! So good.
It didn't hurt too bad, but I always have to look away when they put the needle in. I have no problem with any of it, I just can't watch the needle actually puncture my arm. I bled really good at first, then after like, 10 seconds, I just stopped. I don't know why, they didn't explain it to me, but I started going again, so victory! I think I have a bruise now-my arm hurts now, and there's some definite discoloration!
This has got to be the most boring blog ever, but you know, I'm sharing things that happen, regardless of what is going on.

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.
