I am writing an email to my friends, about a trip. We went walking by a field and the cows came over and were happy to be petted. I want to say "the cows were happy and friendly" but the word I have in my notes is 親しい which seems to be for a close friend, and the word "intimate" is used. The cows were not that friendly ;-)
Seriously, is there another word I can use? Like the equivalent of "good-natured" perhaps?
