You just need to see the advert for Bake Off to know that.
It’s the TV letting you know the countdown to Christmas has quietly begun.
First cakes, then Strictly, then X-Factor and before you know it, Jools Holland will be ringing in the new year.
This isn’t meant to be depressing, it’s just true.
The world spins and the calendar pages turn – happy July, by the way... anyone know how we got here already?
Making it easy to see why we lose track.
Something happened this week which made me realise I’ve lost track of myself, too.
I mean you are always with yourself, so changes are hard to spot.
Sure old photos reveal your hair might have grown, you no longer wear buckets on your head or turn sofas into spaceships.
But on a day-to-day basis, we just carry on.
As I stood watching my car being winched on to the back of a tow truck on Tuesday morning it hit me – I was coping with it a lot better than I did last time.
Which got me wondering – do you just wake up one day and know you’ve crossed the line into adulthood?
Or is it events, and your reaction to them, which makes you realise you’ve grown up?
I am leaning towards the latter.
Especially as I was soon distracted from the impending bill by a ride in the front of the truck and being given a mini to drive for the day.
Perhaps a lot of people wouldn’t even blink if their car gave up... even if it was on the day their editor returned from holiday and while their family were away.
But for me it was a big step.
It was just me – and what’s more I knew what to do, which I might not have realised otherwise.
Best of all, it was all fixed in time to settle down with my World Cup sticker book that night.
I’m happy to grow up, albeit in stages.
