Would you live there, in Watamu?
You spent an unforgettable holiday there, after one week you wanted to extend it by at least another. You walked on the white sand that tickled your feet as it crumbled, you tasted the ocean water in all possible shades of colour and at every tidal height.
You dived off the boat in front of the reef, ate grilled fish and shellfish on a remote atoll, befriended mischievous monkeys at the ruins of the Arabian city, danced in the evenings to the sound of ice in the caipirinha, inebriated yourself with tropical fruit and sunbathed.
You visited a village and were moved when children hugged you smiling, as if you were their new friend, you listened to the stories of mothers who struggle to have a decent living but do not lose heart. You also realised how paracular and pushy the friendly beach boys are, you became enchanted to see simple life situations and realised how much more human life is at a slower speed. 
And when you got out of Watamu... after two hours you were in the paradise of the savannah amidst wild animals, where silence and endless sky reigned and where so-called civilisation seemed unnecessary.
As if to say: if Watamu is already a wonderful escape, what is Tsavo? 
Yes, maybe you would live there in Watamu, but let it remain a holiday, let only the best appear to you, don't expect to have already understood too much, let yourself be carried away by your emotions.
There is something better you can do, rather than immediately thinking of moving to Watamu.
Go back there on holiday a second time!
