The mother and calf swam so close to me. When the mother passed me, I watched as her pectoral fin came up. I knew I was in its path but had to trust she knew I was there. She turned it, last second... it brushed my fin as if she gave me a high five as a parting gift. How magnificent it felt to watch them swim, with mirrored movements of their tails and pectoral fins. The calf was watching. Learning.
