For various reasons some people would like to only show certain people's Profile Pictures on their Facebook Profile page.. could be that person's profile picture with the piercing isn't the image you'd like on your page! (But, they happen to be a close business partner or unique lovable friend, so...)
So, I found a little-known feature in Facebook that lets you decide who shows up in that Friends box. Click the “edit” pencil in your Friends box (see below) and type the names of the friends in the box that says “Always show these friends”. That's it, cool eh!?

This feature does NOT exist on your Facebook Business Page, unfortunately, I hope they might introduce it there too soon! If they do, I'll let you know!
