Seriously... today I had my hair cut. It went from below my boobs to just about touching my shoulders... so a massive change.
DS2 (adult) hasn't noticed.
DH EVENTUALLY noticed once I'd pranced past him enough times swishing my head in an exaggerated fashion 
They are both lovely men. They will both obediently tell me it looks lovely (it actually does look nice thank heavens!) when I point it out, but I honestly think I'd have to get a full face tattoo before either of them noticed something spontaneously!
I know I'm over 50 but I am not ACTUALLY invisible!!!!
