Answer the question about text:

That simple ... Anyway , it was , quite nice to met these people , I kind of ... like them , after all . For the next day we ( I mean Elka and me ) had planned grill . But quite out of the blue , the weather changed -- it rained and that was serious threat to the whole grill idea . Fortunately Elka decided to move our party to the attic of her house and put grill on the balcony , under parasol .

What was the reason to move the grill ?
It started to rain .
