One of the lessons we learn from the soft , gentle skin Hashem has granted us is that we should not bark at people. Trees have rough bark & dogs bark , but we should communicate gently.
On the other hand we need to learn from the Torah when & how to develop a thick skin to ignore insults. The Torah is called the tree of life & it teaches us the good fortune to ignore & be save from 100 evils ( Sanhedrin 7 a. ).
Now may be a good time for a gem of Torah study.
