Well what do you think?
Is it watching the dawn rays of sunlight light up the clouds with colour? Or do you just groan at the thought of the daily grind?
Perhaps a romantic sunset after a perfect summer's day?
Or a hearty meal with all the family gathered together around the table? Or are you just tired after all the preparations?
A hot shower on a cold day is great, but is it magical?
The thump of the front door as it closes after the last child has left for school? But then you face the commute to the office, or the pile of mail on the dresser, or a sinkfull of breakfast bowls.
If you're a mum like me, and even though your kids are your whole world, that moment, that magical moment, is when their breathing slows, their faces relax, and you know you can finally creep out of their room and downstairs. And breathe.
There's nothing like it. It's the end of the day's journey. You might still be feeling a bit hyper or exhausted, but you've reached the destination safely and now perhaps there's a chance to relax.
I hadn't realised quite how much I'd missed it. Until last night. When, most unexpectedly, I found myself child free at 10.30 pm. And I was still awake.
I crept back downstairs, put the telly and the fire back on, grabbed a glass of apple juice - no need for wine! - and just vegetated for an hour. It felt like someone had unscrewed the iron band around my head and switched off the hamster wheel.
I was still feeling calm this morning. Which was just as well....
When's the best moment of the day for you?
