I took a pee on a cow will it hate me?

I'm at my Grandma's farm and was on the upper level of the cow barn and there is a ledge where you can look down at the cows. I was bored and decided to pee on one of the cows down below. When I peed all over it, it looked up to me and gave me a half confused half angry look. I'm scared now, will the pee burn its skin or something. Will it hate me now and tell all its cow friends. Should I be worried about my safety when around it and other cows?
