Pet Peeves: Cropping out other people for your profile picture

As an amateur photographer, I totally understand retouching photos or enhancing them or manipulating them to make them better. What I don't understand however, are people who upload pictures on facebook with their friends cropped out.

What does this say about them? Here are some of my hypotheses.
-My friends are too ugly and I don't want them ruining the picture.
-My friends are really good-looking and I don't want them to look better than me.
-I think this facial expression of mine is really cool and I think I look great.
-I have no sense of what constitutes the right size for a photograph and I must butcher it.
-I don't want people to know I have friends.

Here are some examples. To avoid hurting peoples' feelings I am only using pictures of myself or random strangers.


here is a perfectly nice (albeit a little blurry) picture of some nice happy girls. I decide - this is a good picture of me, let me use it for facebook!

But instead of using that version on my facebook...

I will instead use a 10x10000 version of the picture, complete with some random hand sticking out of nowhere. Nothing is centered right, but at least I get to be the main focus point.

The best ones are when it's a picture of you and one other person at a special event.

You are my special friend because I came to your graduation and we have a special picture together.

But then when this goes on facebook -

Random hand? - check
Weird picture size? - check
Deciding your friend is not good enough for your profile picture even though you went to their graduation? - check

So yea. Every time I see one of these I just chuckle silently to myself because it's so obvious. Actually I admit, I am also guilty of this. But only once! A cookie if you can figure out which one.
