There are certain days in your life when you realise that you’re finally growing up.

The day when your persistent ‘wobbling’ yields up your first milk tooth into your hand.
The day you receive the keys to your own home.
The day you enter a pub and realise that you wish someone would ask you for ID.

And the day you become the Managing Director of your own company.

I’m incredibly lucky. My business partner is fantastic at what she does; is warm and friendly; has a unique approach to creativity that matches my own *ahem*, and actually enjoys handling invoices. She must be mad. Well, obviously: she’s gone into business with me.

But as we entered our accountant’s office, ready to sign all the paperwork that would join us together in a legally-binding partnership (and she hasn’t even met the in-laws yet [good God, what if she's Heather Mills-McCartney in disguise?]), I wondered how this day might impact on me in the future.

After all, I was about to become a Managing Director. Should I therefore start acting like one? By which I don’t mean taking up golf and having an affair with my secretary... I mean actually, properly, finally behaving as though I’m grown up.

Should I adopt a professional image? Wear make-up at all times? Which might actually mean learning how to apply it properly...

When working from home and have no meetings scheduled, should I actually get out of bed dressed before midday?

Would it - horror of horrors - no longer be deemed acceptable for me to wear a badge to the pub on my birthday which reads: “If you fancy me, say so immediately and buy me a pint of Guinness”?

And, just in case a client might indeed one day happen across my inane ramblings on t'internet.... should I stop blogging?

Such thoughts did cross my mind - but I wasn't about to stop the meeting now.

Paperwork duly signed, my official business partner and I left the accountants. We looked at each other. We laughed. And we made our first two decisions as Managing Directors.

One: We didn’t like the title Managing Director. Too stuffy and dull. Nor did we want some bullshit title that doesn’t actually mean anything - like Creative Director.

We were going to be Boss Ladies.

Two: The Boss Ladies were going for a pint to celebrate.

Maturity. Overrated.
