‘Emily in Paris’ star says he partly understands why critics
panned the ‘cliché’ Netflix show

   Despite being a huge hit for Netflix, critics across the board (particularly French critics) have slammed the show for indulging in outdated and offensive stereotypes that present Parisians as rude, sexist, and elitist.
  The main love interest in Netflix’s controversial comedy “Emily in Paris” said he partly understands why critics have panned the show. “I think they’re right in a way,” Lucas Bravo, who plays chef Gabriel in the show, said during an interview with Cosmopolitan.
   The 32-year-old French actor continued: “At some point, if you want to tell a story about Paris, you have to choose an angle. You have to choose a vision. French critics, they didn’t understand the fact that it’s just one vision. They’re like, ‘Oh, this is not what Paris is.’ Of course. Paris is many things.”

Insomnia

   Insomnia is the most common of all sleep complaints. Almost everyone has occasional sleepless nights, perhaps due to stress, heartburn or drinking too much caffeine or alcohol. Insomnia is a lack of sleep that occurs on a regular or frequent basis, often for no apparent reason.
   How much sleep is enough varies. Although 7 1/2 hours of sleep is about average, some people do fine on 4 or 5 hours of sleep. Other people need 9 or 10 hours a night.
  Inability to get a good night’s sleep can affect not only your energy level and mood but your health as well because sleep helps bolster your immune system. Fatigue, at any age, leads to diminished mental alertness and concentration. Lack of sleep is linked to accidents both on the road and on the job.
  About one out of three people have insomnia sometime in their life. Sleeplessness may be temporary or chronic. You don’t necessarily have to live with sleepless nights. Some simple changes in your daily routine and habits may result in better sleep.

The lion and the four bulls
Clarke, M.

  A lion used to walk about a field in which four bulls lived. Many times he tried to attack them, but whenever he came near, they turned their tails toward one another so that whichever way the lion tried to attack, he would have to face the horns of one of them.
   At last, however, the bulls started arguing with each other, and each went off to a different part of the field by himself. Then the lion attacked them one by one and soon had killed all four.

Ieoh Ming Pei

   Born in 1917, Ieoh Ming Pei grew up in Canton, China. When he was seventeen, he went to the United States to learn about building. As it turned out, Pei became one of the most famous architects of the twentieth century.
  Pei is famous for his strong geometric forms. One of his most controversial projects was his glass pyramid at the Louvre in Paris. The old museum had a lot of problems, but no one wanted to destroy it. Pei had to __________ a solution. Many Parisians were shocked with his proposal for a 71-foot-high glass pyramid. It __________ anyway, blending with the environment. Today many people say that it is a good example of the principles of feng shui.

Memories
Maroon 5
Chorus:
Here’s to the ones that we got
Cheers to the wish you were here, but you’re not
‘Cause the drinks bring back all the memories
Of everything we’ve been through
Toast to the ones here today
Toast to the ones that we lost on the way
‘Cause the drinks bring back all the memories
And the memories bring back, memories bring back you
There’s a time that I remember, when I did not know no pain
When I believed in forever, and everything would stay the same
Now my heart feel like December when somebody say your name
‘Cause I can’t reach out to call you, but I know I will one day, yeah
Everybody hurts sometimes
Everybody hurts someday,
But everything gon’ be alright
Go and raise a glass and say,
Chorus
There’s a time that I remember when I never felt so lost
When I felt all of the hatred was too powerful to stop (ooh, yeah)
Now my heart feel like an ember and it’s lighting up the dark
I’ll carry these torches for ya that you know I’ll never drop, yeah
Everybody hurts sometimes
Everybody hurts someday,
But everything gon’ be alright
Go and raise a glass and say,
