Today Barnaby was sitting under a tree in Morocco, minding his own business, when what should hit him but a shower of olives!  

Way back in May in Turkey, he'd seen little flower buds on the olive trees.  By the time he got to Greece the flowers were out.  Then in Italy he saw actual olives, although they were way too small and hard to eat.  Even in Spain in September, they looked ripe but weren't quite ready.  Finally, he thought - they're falling off!

But when he took a closer look he realised they weren't.  There were wrinkly black ones, shiny fat purple ones, and hard green ones - all coming from the same tree.  And in fact, there were ladders.  With people up them, pulling the olives off the branches by hand.  He thought maybe they were picking them too soon, but when he asked, they told him that it's best this way - they wanted all three colours to cure and to make tasty olive oil with.

And when he tasted one, he found out they're still too bitter to eat!  He's just going to have to wait until they're cured.
