This nonsense has got to stop

I have noticed a disturbing trend among the the youth of today: they have the tendency to grow up.

WHAT'S UP WITH THAT? 

To prove my point, I have provided three clear groups of evidence.

1. 

These two used to be this size... 

...but now they're this size.

2.

This one went from this...

...to this.

 3.

This one thought it would be perfectly acceptable to go from small...

...to tall.

Then again, maybe I shouldn't be talking. I went from looking like this...

...to looking like this.
