you see, i was walking with my dad and my bro, we were visiting our old warehouse that never been taken care, but when i going outside, i stepped on a fricking nail (it penetrate to my crocs too) i thought it was a rock until i look closely it's a nail and blood, so my dad squeezing my wound so the infected blood got out, after that he put a bandage (note, my dad did step on a nail too but with his thick sandals it almost got in)
