I so felt that the presence of the butterfly while we were praying signifies her presence my dear friend, @mipiano . Sometimes, I am believing in superstitions. And surely, the pigeon that visited your friend is the one that passed away. It may give us a deep feeling of sadness, but this is life, all we have to do is to accept a hardest truth.
Thank you so much dear friend, mipiano for being so nice to me and my sister, especially for remembering erikasue as one of your friends. You are very appreciated. Have a nice time and take care.
