Claire - I don't think you question your decision to remain gray as much as you believe. You've already made your choice to have a healthy head of hair that's not colored. The difficulty seems to stem from the public perception that you are older than you are. I think you're a lot more comfortable with that misperception than you are with the inevitable thinning of you hair if you colored it.
I struggle with that myself albeit not to the same degree. I am about 10 percent gray and I wonder if I do extra moisturizing conditioning treatments etc. if I could avoid breakage, but it simply isn't a risk I'm willing to take. My hair colored is not as soft and feels brittle and scratchy.
Hil - well said. It seems the struggle is accepting that what we have is all we're going to get. There is so much pain and suffering we cause ourselves when we wish for things we simply aren't going to get. Perhaps that's the human condition to realize this then move on to having a happy life.
Soobee - Is the instyler that tool where you blowdry your hair inside of an attachment and it spirals on itself until it's dry? I thought that was pretty cool but I wasn't tempted to get one because my hair will probably not get long enough to take advantage.
Goldenpig -- isn't that the way of it? The grass is always greener? DH constantly refers to me as "My Michelle". I call Michelle O his girlfriend and his crush. I agree the styles are Michelle-ish, it's a very flattering and classic style.
Alaskagirl -- I always wanted to be taller too. I think it's funny that in real life and on the forum people think I'm taller than 5'5" so maybe I got my wish?
Lisa -- I'm just glad bright colors love me back. I'd be out of business if they didn't. I've always been a bit afraid of neutrals because I thought if I wore too much of them I'd fade into the wall. I'm sure that isn't really true but it doesn't stop the thought from invading my brain when it comes to choosing colors for my outfits.
