STUCK IN unbelievably wet mud

I do not believe it my luck is really bad I am unlucky enough to go to the park on sunny day, but it has been raining the other night so it was wet I don’t mind that what I do mind though is all the mud and that’s not even the worse part. So I am running in the park with trainers on and suddenly there is so much mud I can barely walk in the end I was beyond caring and that’s when it all went wrong. I was coming back on the track that lead me to the waterfall when I found shortcut. then guess what happened go on have a guess maybe I slipped maybe I fell into the water running nearby NO I got stuck IN QUICKSAND QUICKSAND. No I am not mistaken it baffled me too luckily I got out, but the mud is still clinging on to my feet after 5 washes 5 WASHES. I’m surprised I didn’t sue the park for trauma or whatever you call it.
