never done anything serious!!
when i was little i was messing on the sofa with the dog and leant over the arm to pick up the food bowl and somehow cut my head open on the corner of a cabinet.
then a few weeks ago i fell down the stairs because @cupcake; made me get her a glass of water before going to bed and i slipped and landed right on my side on the steps, was in pain for a week or two after!!
