Being in lockdown and all of that, options for him were sadly limited.
His choice of activity was therefore to drag us all up a mountain to have a picture taken beside something called a triangulation pillar. That'll be the tenth such lump of rock he's reached over the past few weeks which is good for his Scout badge collection.
Happily, Vanessa brought a little cake along to mark the occasion (and replace the lost calories from a five-mile trek).
On our return, we threw a little barbecue in Jamie's honour with steak as the main course. That's unless your name was Charlotte who requested a microwave pasta meal from M&S. Anything to avoid my cooking.
And the birthday boy received another cake in time for dessert, a full size one this time.
There isn't any left.
The week has been book-ended by Father's Day last Sunday (loved my card)...
...and the "Glasthomebury Festival."
With the 50th anniversary of Glastonbury canned because of you know what, a wise social media person came up with the idea of everyone recreating the festival experience at home for the entire weekend.
How far you're prepared to go is obviously a matter of personal choice.
Jamie and I have camped in the garden for the past two nights.
Under a makeshift Pyramid Stage.
Vanessa and Charlotte kind of joined us last night by sleeping on camp beds in our converted garage.
However, as someone once said, it's all about the music.
And thanks to the BBC showing wall to wall highlights from previous years, there has been plenty to choose from.
Amongst those acts I have insisted we watch are Katy Perry, Coldplay, REM, Katy Perry, James, The Killers, Katy Perry, Kenny Rogers, Neil Diamond, Katy Perry, Shakira, Status Quo, Katy Perry, Adele, U2, Katy Perry, Happy Mondays, The Verve, Katy Perry, Oasis, The Waterboys, Katy Perry, George Ezra, Katy Perry and Katy Perry.
I was never a huge David Bowie fan, but we will watch him tonight although I hope there may also be some time for a burst of Katy Perry.
One thing I've particularly enjoyed about watching scores of performances is the sight of large crowds of people enjoying themselves.
And whilst I appreciate that a high percentage of Glasto-goers are off their faces, the images still serve as a timely reminder that we can all have festival fun again one day.
