Understand your feelings. When we're diving, on the few occasions we've seen a shark it was awesome! When snorkeling or swimming it's different for me. Snorkeling at the entrance to Lee Bay we saw a 4' nurse shark 30' below. I casually made my way back to the dingy. When DW got back she asked why I came back so soon. Before I could think of a good reason she just shook her head and said "little Susie".
