Nature has made numerous countless things including germs that can harm or even help. In fact you can look upon this world as a big gymnasium or school where, on the one hand we have teachers that help us learn or inspire us or give us hope and beauty and light by their presence. On the other hand there are creatures that oppose, challenge and even threaten. They too end up helping by making us strong and wise and eventually grow fearless.
Affectionately,
