Thoughts running through my head...

... on discovering a grey hair in one eyebrow this morning.

• Is that what I think it is?
• What the...?
• No, I mean, what the...?
• You have got to be kidding.
• Where did that come from?  It wasn't there yesterday - was it?  Or has it been there all week, all grey and wiry in plain view and - oh, the horror - everyone else has noticed but nobody has wanted to tell me?
• I'm too young for this shxt.
• Should I pull it out? *Reaches for the tweezers*
• Should I leave it?  *Puts the tweezers back down*

• Blink.  Breathe.  Take another look.

• Shxt.  It's still there.

• I'm going to pull it out.
• No, wait!  If I pull it out, will 2 grow back in it's place? 
• I don't care.  If I leave it, it will just get longer and longer and take over my face.
• OK, I know that doesn't happen with my other eyebrow hairs but this is new, this is alien.  I have no idea how this blighter might behave.
• I'm going to pull it out.

• But - is that sensible?
• I mean, am I going to pull out all the other grey / white hairs as they appear?  Because if I do, eventually I will be left with no eyebrows at all...

*Pause for reflection*.

• Get a grip, woman.  It's one eyebrow hair.  
• I could dye it...
• No, don't be ridiculous.  Dye all my eyebrows for the sake of one grey hair?  I don't dye the hair on my head and there is a lot more than one grey hair in there...
• Yes, but this is different. Somehow.

• Pull it, pull it, pull it!

• There.  Doesn't that feel better?

• Stop checking, woman!  It's gone.  The sneaky little...

Tell me, blogosphere - at what stage should I give up the fight?  And how do you deal with this particular indignity of aging?
