This is a Bubble.

Actually, it's a not very good picture of a bubble.

The problem with bubbles is that they pop.
Splattering bubble mix on to camera lenses.
Then, when you try to wipe the splatters off with a lense cloth, the splatters smudge.
Then when you try to take better pictures of bubbles you can't, because your camera lense is smudged.
Then when you try find your Dad, because he's good at removing smudges from camera lenses, you discover he is out.
So you are stuck with whatever pictures you took before you smudged your camera lense, because any future pictures you take will be smudged.

So, yeah, I have a smudged camera lense.
;D
