I know a couple of those "skinny" people. I would not want to be them, they are miserable, unhappy creatures. One is very cute, probably a size 2 except for the fake boobs, which look fake, married for money, has 2 darling daughters, but is in the throws of a nasty divorce because 1 bed was not enough for her. Now she's messing around with a guy who is known to be a player, nasty, manipulative and controlling, also the one she got caught with, the ex never found out about the girl sex parties.
The other married for money and only money. She spends all her time traveling the competitive clay shooting circuit. She is part of the girl party mess with the above mentioned. Along with other things when she's out of town.
These ladies put on a good front while they're at home, church, book club, teaching fitness classes, very active in the community, in the local paper a lot.
They appear on the outside, to be what a lot of think we want to be, cute, thin, in shape, comfortable money wise, well thought of in the community, etc. but despite all that, they are miserably unhappy women.
So, skinny isn't always all it appears to be.
As for myself, I'm not built to be a 2. 10-12 works for me, I'm comfy, have curves and still look good. And most men do like a few curves, my Dad used to say he didn't want a super skinny woman, he didn't want to have to shake the sheets to find his bacon and eggs.

My boys married girls who are fit and look good, but still have some those great curves that men like to grab on to!
