That's a shame. 
Yes. It is.
August 19th, 1988, our eldest daughter died from complications arising from pneumonia. 4 years earlier she needed a blood transfusion. Just one of your typical bits of kids stuff - stepped on a chunk of broken glass on the beach and bled badly. She'd have probably been fine without it, but the docs decided to give her a pint as a precaution.
Then - hey, suddenly she got sick. Didn't have clue bleep one what was going on - HIV wasn't even on the radar back then. It was a scary thing to learn. Got back from the funeral - wife didn't go, she adored Louise - and found that every single picture of Louise missing and a pile of ash in the fireplace. To this day, my missus will never refer to her or mention her name.
These scum bleep can bleep off and die painfully. I mean, if they KNOW they have it and still have unprotected sex or give blood, they should be treated as what they are. Murderers.
