Ah, Betsey... the ultimate question... How long will this take??? And if he is willing to get wet, why NOT go swimming... but as you said, they seem to have been shark bait before...
So, we must have the patience to Keep Swimming and keep watching... if we pursue them, they will rapidly swim off... just have to keep the waters calm, safe and warm and let them find their own way into our little harbor.
Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
