The woman laughs as Echalote nuzzles her arm the same way that dogs use their snouts to get their humans' attention.
The older donkey at the end of the video is Echalote's mother, Anisette. Both live together at the Bel'âne Farm in southern France, where people occasionally visit and play with the animals. Though Echalote seems to have taken a liking to this particular woman, Bel'âne told the Dodo that "Echalote is a little donkey who's cuddly with ALL the visitors."
Maybe one of the reasons Echalote is always in good spirits is that she lives in one of the most scenic locations on Earth. Since Echalote and Anisette live in the French Alps, they spend every day in the middle of beautifully green mountains, as seen in the photo below.
