CSS prevent div flex from stretching child

Question

The moment div has the flex display property it stretches the paragraph. I seem to be missing something but no property I can think to put on the flex div changes this. How can I prevent this behavior? (without the flex property I get the result on the right in the image)

div {
  display: flex;
  justify-content: center;
  flex-direction: column;
  height: 200px;
  width: 100px;
}

p {
  background-color: green;
  display: inline;
}

<div>
  <p>
    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod
  </p>
</div>

Answer 1

add another wrapper:

div {
  display: flex;
  justify-content: center;
  flex-direction: column;
  text-align:center;
  height: 200px;
  width: 100px;
}

p span{
  background-color: green;
}

<div>
  <p>
    <span>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod</span>
  </p>
</div>
