I once went to give blood. The woman was so darn rude that I'll never bother again. She treated me like some stupid kid - I was waiting to see my doctor, about HAYFEVER but because of that she completely dismissed me and wouldn't even let me explain that it was only a routine appointment and nothing serious, so I wasted all that time and money travelling there for nothing - I was only 17 at the time so I couldn't afford to just take trips out to health centres 20 miles from my home just for the fun of it.
I also get letters at least twice a week to my uni address, despite the fact that I've never ever given it out to them. It makes me so angry that they're allowed to do that, I can't believe that they actually get people to donate by pestering them by mail. I don't mean to sound heartless, but how important is it that I give blood anyway? I have the most common type around and we were always told at school that there was no shortage of that anyway.
