Thank you, Sherry!
I tend to be careful of my comments, even in real life when I have visual clues. I used to be <cough> a little too forward.
YOUNG ME: “What the hell did you do to your hair?”
OLDER ME: “Your hair looks nice. What the hell did you do to it?”
EVEN OLDER ME: “So… you look nice.”
And let’s face it, you never know when you comment on someone’s work (or hair!) whether they spent two minutes dashing it out or two days tweaking it to perfection.
