I do not leave comments but on rare occasions. If you leave me a comment, I may comment back, but probably not. I simply don't give a flying fuck about it. I don't care if you leave 1000 comments on my page, its not going to entice me to go to your page and leave a comment.
Nothing more annoying than hitting someones page to leave a comment, and having to wait 3 mins to leave said comment, due to all the other fucking comments loading.
