Tool tip for the post icon

Dear Induslady,
Whenever I write a new post, I get an option of choosing an icon for my message
Post Icons
You may choose an icon for your message from the following list:
No icon ..............

This question is there in my mind ever since I have joined the site, is that the icon that has the thumb up (third from start) has got the "tool-tip" saying thumbs down and the thumbs down icon(last) says thumbs up
Not a big problem though... he he...
