"They have everything they need, they have medical care, hot food...... Of course, their current lodgings are a bit temporary. but they should see it like a weekend of camping"
Well Silvio for starters when you go camping you generally have a home to head back to when you want to or get tired of it: with all the home conforts available.
Secondly if what the people of the towns and villages affected have been saying is right they are bing told they may be out for at least 3 months, hardly temporary if you want them to be camping though that all.
Best to think before engaging the tongue. Not very sensible way of putting it.
