Another weekend alone

My sister and I had another weekend alone with my parents at the grand canyon. We had two of our friends come over and we got into a competitive game of truth and dare-mostly dares tho- and my friend got a dare to jump on the trampoline with this pair of slipperly shoes on with baby oil on the tramp and on the bottom of her feet. So she did it and said it was really fun so my sister did it and told me i should try so i got on the tramp with paige still on as she was taking off the shoes to give to me(remembering this is reallyreally slipperly) she fell and grabbed onto me to try to pull herself up but instead she took me down with her and i swear i was knocked out for a second cuz everything was black i couldnt see for about almost 2 minutes and like 5 minutes later i had this HUGE lump on my forhead!!!!!
