If that's you're "thing," then fine. I'm rather libertarian when it comes to how a woman decides to augment her boobs.
Although, it does make me wonder if she took back health into consideration.
My ex-girlfriend had massive mammaries, as did her mom and two sisters.
They also share the same back problems.
The novelty/vanity may be "fun" now, but somewhere down the road, this woman is probably going to have to fork out more money to have a fairly involved reduction procedure.
