I will never run again!

I was trying to be a hip parent and chasing my son outside he loves it when I chase him, but unfortunately this time I wasn't looking very well and I tripped over something I fell hard and injures my knees and hand, it was awful I sat there for a while and he just kept running didn't even care to check up on me, I remember when I fell as a child it didn't hurt this much and I was okay in few hours but this time it was very painful and still didn't heal , my parents never played with us like that so I was trying to give him the fun childhood I never had, my childhood was very boring mostly playing outside by ourselves.
