I fell backwards and literally sat/slumped against a cactus when I was 7. I was watering the plants and backing up when I tripped over the little walkway in our yard. I couldn't even pull myself off of the damn thing because the thorns were digging into my back. Needless to say it hurt like hell. Took about four days of plucking needles out of me to end it. I remember screaming and crying so much that I'd just pass out from exhaustion. Then there was trying to sleep on one side without rolling over on the thorns. All I could wear for clothes was a huge T-shirt because yes, the needles were down THERE too. All in all, pretty awful experience.
