Delete comments
 

my english is kind of.... well, a bit difficult. Shir story, I posted the wrong words on the wrong pic and I don't know how to delete it

The delete link should be available on your comment, on the right side.

If you don't see it, it's possible you don't have the ability to delete comments yet as you are still a probationary user. You'll need to participate more in the site to upgrade your user level (A minimum number of posts are required, I don't recall how many off the top of my head).
