Is this talking about at he blessed hope, or at the second coming?

Luke 17:26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
 27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.
 28 Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
 29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
 30 Even thus shall it be in the day when the Son of man is revealed.

They are eating and drink like it is a normal day.
That for sure will be the case at the blessed hope.
It sure looks like there will be horrific things going on in the world right before the second coming.
Either the horrific things are not totally world wide, and some places, like Babylon are living deliciously.
Or people get hardened to the horrific things, and intend unrepentantly to live as normally as they can.
Or this is speaking of the blessed hope.
Which is it?
Or is there yet an even better explanation?
