A greeting, a farewell, a term of endearment, a wish of sympathy, a sign of joy.....
Watch elephants and you will see them use this gesture. If you have ever had the opportunity to see dear Shirley and Jennys reunion and their lives until Jenny passed away, you saw them do this often....tender touches between mother and child.
Our girls in Sanctuary do seem to use this gesture often.
Tender trunk touches....
