Do Blondes Really Have More Fun?

So I am thinking of changing my hair color. I've been a blonde all of my life (see below), but I think it's time for a change. Until about 4 years ago, I've been a natural blonde. And then, for some strange reason, I decided that I wanted to start chemically enhancing my (already blonde) hair. Great idea. Now, every couple weeks, I need to touch up my roots (which are apparently really pissed that I started dying my hair in the first place because they now grow in a nice shade of dark brown...). What it comes down to is that I'm tired of dying my hair but I am too vain to just let my roots grow out. In addition, I really like being a blonde. It's all I've ever known and I don't like change. So, the solution that I am currently mulling over is to dye my hair brown in an attempt to allow my roots to grow out and eventually get my hair back to it's natural color. Any thoughts? 

Me, very blonde at age 4. Can you tell how excited

 my cousins are to watch me open Christmas presents?

Will Harper still recognize me if I dye my hair brown?
