How do you handle critics?

I don't think it's that easy to receive criticism; No one likes to receive it, and I can understand why many people think its hard to reat normal to it. From my own experience: All the people I heard getting criticism didn't react very well.
For example, I gave my friend a bit criticism, and she immediately began attacking the way I put it, and didn't do anything with the criticism itself. Ofcourse, there are better and worse ways to give it, but after explaining she didn't talk to me anymore.
I won't get into details, but I'm just trying to say that I think its hard to recieve criticism, and that there are only a few people who will see it as constructive, or being for the better.
