Donate blood? i think not

I have know learnt after yesterday afternoon that i should wait a good 20minutes like the murse said after giving blood. i hate you stubborness and wanting to catch the bus. so i left 10 minutes earlier. I than got to the bus and felt feint so of corse i feinted, twice, hitting my head on the bus and fell back on cement and woke up in my own vomit making a specicul of myself. Not that i can remember any of it. kudo's to everyone who helped me.
