Ah, today I've a bad news and a good news.
First, the bad one. I had a slight injury in my feet either a thorn pricked into it somewhere or something sharp ...may be a small glass piece made its way onto the skin of my foot. It was a real oain to walk after that. My feet were also very dirty and it was almost dark out there, so I couldn't figure out what exactly was there in my feet. So I continued walking but very slowly and mostly not letting the pressure on the part where I was feeling pain.
Good news is that I could complete my 10K count in spite of it. However, I reached to my room earlier than usual. And was happy to see that my foot wasn't bleeding as I suspected. I figured out it was some prickle which I need to pull out. But I'm tired today and will try for it tomorrow.
Thanks for reading this @stupid account!
