Undeniable Signs of Aging

When do we stop growing 'up' and begin to grow 'old'? 

Is it when kids expose the obvious generation gap between you and them by addressing you  as 'Madam' / 'Sir'?

In my particular case, there was that (aren't kids lovely? - sense the irony there) but most importantly, what the event triggered: acceptance. Admitting to myself that, although I still love doing some of the same things that I did years ago ("but I'm not old! I still like to do what young people do!"), the reasons for doing them couldn't diverge more.

Here is what I'm talking about: 

1. Dyeing my hair

'Sunkissed brown', 'golden bronze', 'deep copper'... My hair has seen (and in some cases suffered) a wide range of shades and highlights.
Motivation behind it:

   · Before: new looks

   · Now: new greys

2. Wearing my headphones on the go

During my daily bus commute, walking around town, at work...My headphones plugged in to walkman (yes, I'm that old) > discman (told you I am!)) > ipod > and now phone.
Motivation behind it:

   · Before: listening to brand new hits

   · Now: cancel the noise of world - I confess: there times when no music is coming out of them :)

3. Longing for the weekend
All week waiting for Friday, thinking about the free days to come.
Motivation behind it:

   · Before: Go out with friends till dawn and go out again the following day.

   · Now: Curl up under a blanket on the couch with a good book and a hot tea. My weekend plans are the best!
