M15 showing my age

My neighbor, an elderly woman, came to ask for my help while I was getting ready to leave. I ofcourse said yes but bc it was so hot I said I'm going to start the car 1st and let it cool off then I'll be right over. I put my foot in to push break and hit button and as I get out my foot goes half on the driveway and half off and down I go. I don't recall ever falling so clumsily , she asked if I was OK and I laugh it off embarrassed. It was definitely something that would not of been a big deal 10 years ago but now my knee is all scraped
